Keeping Your Pet’s Microchip Information Up-To-Date is Essential

If you want to be proactive about saving your pet’s life, regular veterinary visits, pet insurance and keeping a cat indoors only are certainly high on the list. But the most powerful tool of all could be about the size of a grain of rice: a microchip.

Sometime over the past month or so, HomeAgain, a lost pet recovery service and microchip provider, reunited their one-millionth pet with the owner. (It was a challenge to tell exactly which pet was the one-millionth recovered because so many pets are found through HomeAgain — about 10,000 each month!)

Sadly, one in three family pets will get lost during its lifetime, and without identification, around 90 percent will not return home.

The Baumgardner family, of Lompoc, CA, lost their Pekeapoo, Chewie, two years ago. Ultimately, a microchip made reunification possible, but it took a while.

While the family was living in Arizona, Anita and her husband went out to dinner one evening, leaving Chewie and Jack, a Cocker Spaniel/Labrador mix, at home with the couple’s then 18-year-old son, AJ, and daughter Gaby, 13.

Jack likes to open doors, and as AJ snoozed on the sofa, the pooch slipped out the front door. While Jack strolled only a few feet away to catch some sun, Chewie zipped past him and kept on going.

“When we returned home, we searched the neighborhood, but it was already dark,” says Baumgardner. “We assumed in the morning Chewie would find his way home.” That never happened. The family notified HomeAgain, called local shelters, a local pet store and Chewie’s groomer, all to no avail. Time went by, and eventually the Baumgardners moved to Lompoc, CA.

“We all knew Chewie might have been hit by a car, or who knows what,” says Anita. “The hope was that maybe he was picked up by another family who just didn’t check to see if he had a microchip.”

Having a microchip alone is of little value. It’s like having a cell phone without a phone number. Pet owners need to register their contact information with the microchip provider and keep it up to date. Anita did provide new information when the family moved. In April 2012, she received a call from HomeAgain stating, “We have your dog.”

“I told them, ‘you must be mistaken. My dog is right here,'” Baumgardner recalls, referring to Jack.

“No, it’s Chewie,” said the caller.

“Well, this was two years later. I nearly fell out of my chair,” Anita recalls. It turns out Chewie had been spotted walking along a road and was picked up by a good Samaritan. The pet lover did the right thing, having Chewie scanned for a microchip at a local shelter. Because his registration information was up to date, HomeAgain was easily able to contact Anita.

Family members promptly headed to Arizona to pick up Chewie. Shelter staff said that even before Anita and Chewie were reunited, the dog heard Anita and clearly recognized her voice – even after two years. The reunion was joyous on all sides.

“Chewie looked pretty good. He’d even gained some weight, though he had a few missing teeth,” says Anita.

No one knows exactly where Chewie was for two years; perhaps he’ll write a “tell all” book.

Gaby was especially elated about the reunion. She posted photos every day for weeks on her Facebook page.

“Our dogs are a part of our family, and very important to us,” says Anita. “I think most people feel that way, which is why I’m such an enthusiastic supporter of microchipping.”

Of course, without this service, many of the one million animals recovered through HomeAgain would have been euthanized.

“Our family is sure grateful,” Baumgardner says.

For more information on microchipping, consult your veterinarian.

Pet-Safe Spring Gardening Tips

With a little planning, creating a beautiful garden that is also pet-safe is doable, writes emergency veterinarian Denise Petryk, who provides a list of toxic plants and dangerous fertilizers and chemicals. Younger animals will eat anything and are at higher risk for toxicity, but even exposure to small amounts of some toxic garden components can be harmful to pets, Dr. Petryk warns. The Seattle Times/Tails of Seattle blog (5/10)

AVOID the 10 most dangerous, most toxic plants:

foxglove.JPG

— Castor bean (Ricinus communis) — oral irritation, vomiting, diarrhea, kidney failure, convulsions, death.

— Foxglove (Digitalis purpurea), pictured right — vomiting, diarrhea, weakness, cardiac failure, death.

— Japanese Yew (Taxus cuspidata) — tremors, difficulty breathing, vomiting, seizures, death.

— Jerusalem cherry (Solanum pseudocapsicum) — vomiting, seizures, depression, trouble breathing.

— Lily of the Valley (Convallaria majalis) — vomiting, heart trouble, disorientation, coma, seizures.

— Lily (Lilium species) — kidney failure in cats — ALL parts of the plant, even in small amounts.

— Morning Glory (Ipomea sp.) — vomiting, diarrhea, agitation, tremors, disorientation, ataxia, anorexia.

— Nightshade (Atropa belladonna) — drooling, vomiting, diarrhea, depression, slow heart, weakness.

— Oleander (Nerium oleander) — diarrhea, trouble breathing, tremors, collapse, incoordination.

— Precatory Beans (Arbus precatorius) — severe vomiting and diarrhea, tremors, fever, shock, death.

The 10 most common plants that can cause drooling, vomiting, diarrhea — AND if ingested in larger amounts — more serious health problems:

hydrangea.JPG

— Hydrangea, above

— Azalea

— Boxwood

— Daffodil (bulbs are more toxic than leaves and flowers)

— Tulip (bulbs are more toxic than leaves and flowers)

— Rhododendron

— Iris (Gladiola)

— Elephant’s ear

— Clematis

— English ivy

The 10 most surprising problem plants:

— Apple (the seeds contain cyanide)

— Plum, cherry, apricots and peaches (the pits contain cyanide)

–Onions, chives and garlic (cause anemia)

— Potato and rhubarb plant leaves (vomiting)

There are some wonderfully safe annuals and perennials:

–Violet (Viola sp.)

–Yellow Corydalis (Corydalis lutea)

–Zinnia (Zinnia sp.)

The non-plant concerns in the spring include fertilizers, pesticides, slug bait, mulch, and garden tools. Talk to your local nursery about the safest options, read labels carefully and store everything safely in sealed containers or out of reach.

Try natural products like vinegar for weeds, coffee grounds, beer and salt for slugs, and soap and water as a natural pesticide.

Avoid cocoa mulch as it comes from chocolate manufacturing and can contain substances that will cause minor chocolate poisoning (vomiting, diarrhea, hyperactivity) as well as general irritation to the mouth, stomach and intestines.

Many of our mature dogs (and almost all of our cats) are discriminate — they might sniff but they are not inclined to eat plants.

Grass is often the exception and in small amounts, common grasses are safe. Ornamental grasses can be very irritating to the mouth, throat, and nose so if you have a big grass eater, it is safest to avoid these plants.

Remember that puppies and kittens are always an exception. They will generally eat ANYTHING! It still makes most sense however to always pick the safest plants possible for our spring flower gardens and our deck pots.

Horticulturists employed at our favorite plant nurseries are excellent resources for pet safe plants and gardening products. The ASPCA Animal Poison Control Center has a fantastic guide to pet-safe gardening and a wonderful collection of plant pictures and toxicity information here . PetPlace.com also has an array of informative articles written by veterinarians about toxic plants and gardening.

The three most common spring garden problems we see in our busy Tacoma pet emergency room include dogs ingesting SLUG bait poison (metaldehyde), dogs ingesting decomposing things out of the compost pile, and Lily ingestion or sniffing by cats.

A few bites of slug bait can cause horrible tremors. Quick emergency treatment is critical.

A compost pile snack can also cause tremors or it may cause drunk-like behavior or vomiting and diarrhea. Here too, quick emergency treatment is essential for a quick recovery.

Lilies are highly toxic to cats. It is safest to avoid all lilies — both as cut flowers as part of a bouquet or as a garden plant. Potential sniffing of the flower and inhaling the pollen can even be a problem to our cats.

Enjoy your garden but do your research first. Prevention is so much easier than sick animals and treatment.

Cardiac Disease is Prevalent in Pets

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       Heart disease is common in dogs and cats and can be an important cause of illness.

Unlike many other health problems, heart disease often profoundly limits a pet’s survival. An important statistic for pet owners to consider is about 10 per cent of dogs that present to veterinarians for care suffer from heart disease. In cats, it has been reported 15 per cent of apparently healthy cats have an underlying heart condition.

What these two statistics clearly tell me is heart disease is prevalent and therefore annual checkups play a vital role in the early identification of heart disease and helping keep your pet healthy.

Heart disease in dogs and cats falls into two categories: congenital and acquired.

Congenital problems manifest at birth and can be due to genetically inherited disorders or arise from problems during pregnancy. Acquired disorders are more common, and usually develop in adulthood or old age.

Recent research in veterinary medicine has identified some inherited disorders that occur later in life in purebred dogs such as the boxer and Doberman pinscher, and in purebred cats such as the Maine coon and ragdoll. In the past several years, genetic tests have been developed to identify these heart disorders and more will be available in the future.

An annual checkup is one of the best opportunities to identify heart disease in dogs and cats.

The annual physical examination includes an assessment of the heart with a stethoscope and evaluation of the peripheral arterial pulse. This examination allows your veterinarian to identify heart murmurs and arrhythmias, and assess if the heart is too weak.

Heart murmurs occur when there are leaks in one of the four heart valves or one of the valves does not open completely. An abnormal communication in the heart can also create a murmur. Arrhythmias are abnormalities of heart rhythm, causing the heart to beat irregularly, or too slow or too fast.

Many forms of heart disease result in a weakened heart, which in turn can lead to heart failure, where the heart cannot pump a sufficient amount of blood through the body. While continuing to work harder to pump blood, further heart damage can occur.

Early detection of these abnormalities through regular checkups helps your veterinarian identify the cause of the heart abnormality and its severity, which goes a long way toward early treatment and offers the best chance for a cure or long survival.

Depending on the nature of your pet’s heart condition, your veterinarian has an array of additional tests to help identify and assess the severity of the heart disease. Chest X-rays are used to evaluate heart size and reveal congestion in the lungs, which is an indicator of a weakened heart.

An electrocardiogram and 24-hour holter exam can assess the heart rhythm. A cardiac ultrasound exam measures the strength of the heart and identifies structural defects. Recent work shows that early treatment with medication can have a significant effect on both survival and quality of life.

As well, many congenital disorders can be treated and cured, but early detection and intervention are key to a good outcome.

The annual checkup is also the best means to help dog and cat breeders identify the healthiest purebred dogs for breeding purposes. This is an important way to limit the number of puppies with congenital and inherited disorders.

In conclusion, annual checkups are an essential way to keep your pet free of clinical signs of both heart disease and other disorders.

No Excuse for Skipping Rabies Vaccination

The Carlsbad, New Mexico area just suffered through one of the worst rabies outbreaks in the state’s recent history. Over a three month period from the end of 2011 to the beginning of 2012, 32 dogs, 1 cat and 10 sheep had to be euthanized because they had been exposed to a rapid fox. During that December, January, and February tests also showed that 22 skunks in the area were infected with rabies.

 

What makes this outbreak especially painful is that almost all of the euthanasias could have been prevented if only the pets and livestock had been up-to-date on their rabies vaccines. In addition, twelve people in the Carlsbad area had to go through post-exposure prophylaxis even though no one was directly exposed to rabid wildlife. In one example, an unvaccinated dog came down with rabies and the entire family — all eight people — needed to get expensive, post-exposure prophylaxis according to Dr. Paul Ettestad, New Mexico’s state public health veterinarian.
I just don’t get it. Why do so many people fail to protect their pets and themselves from such a deadly disease when safe and effective rabies vaccines are so readily available? I understand when people can’t spend large amounts of money on a pet when the budget is tight, but that’s no excuse when it comes to rabies vaccines. They are dirt cheap. In fact, with a little research owners can oftentimes get them for free. In Colorado, 73 veterinary clinics just took part in a campaign providing complimentary wellness exams and rabies vaccinations to over 1,047 pets. Similar events can be found all across the country.
The only dogs or cats that I don’t recommend receive rabies vaccinations on the schedule dictated by local regulations are those that have had a documented anaphylactic reaction (i.e., a life-threatening allergic reaction) to a previous rabies vaccination and those that are so sick that the risk of vaccination outweighs the benefits. In these cases, veterinarians usually need to fill out a form or write a letter to the appropriate regulatory agency explaining why they have declined to vaccinate.
I don’t consider healthy old age or indoor only status a good reason to skip rabies vaccination even though I often recommend against vaccinating for other diseases under these circumstances. Why? Because if one of these pets is ever exposed to an animal that is known or suspected to have rabies or it ever bites someone, it’s lack of current vaccination is going to spell big trouble.
Many owners have heard of the ten day quarantine that is typically mandatory after a pet has bitten someone, but the situation is even more serious when a pet is exposed to a potentially rabid animal. Dogs and cats that are current on their rabies vaccines generally receive a booster vaccine and are quarantined for 45 days or so (this can often be done at home). However, if your pet does not have a current rabies vaccine, euthanasia is the most likely outcome. If you do not permit this, a strict quarantine of six months or longer will imposed, most likely at your expense.
Are your pets current on their rabies vaccinations? If not, what’s your excuse?

Euthanasia Means “Good Death”

If you are an animal lover, your pet is probably one of your best friends. When that best friend is facing the end, it’s tough to say goodbye.  In this NBC29 Special Report, we look at the difficulty of deciding when it is time to say goodbye and your options afterward.

When animal lovers adopt a pet, they make a commitment to care for them, even when they’re sick and close to death. Most humans will outlive their companions, and the end of life for pets can bring deep grief and raise a load of questions.  When that happens, we humans get very emotional.

When dealing with a pet with a terminal condition, people often have a difficult time deciding whether to euthanize, or when the time is right to end their companion’s suffering.

John Dove has two cats, Krogie and Mocha, and cherishes the friendship he has with them. “I don’t have any children, but if I had children, I don’t think I could love them any more than I love my animals, they’re my kids essentially.”

Dove recently experienced the profound pain of losing an animal when his 12-year-old cat Scamper had a stroke.

“And then all of a sudden, he let out a yelp and I looked around at him and he was hyperventilating very heavily, so it looked like something was really wrong,” he said.

A quick trip to an emergency veterinarian divulged the dilemma a lot of pet owners face. “So at that point I had to make that very painful decision.”

Dr. John Andersen deals with clients who face euthanizing their beloved pet. “We’re in control and there’s a time we just have to make that really hard decision.”

Dr. Andersen is not only a pet owner, he is also a veterinarian in Albemarle County and says he understands the deep human-animal bond. “They’re a best friend, they’re kind of a confidante, they’re an explorer with you, they provide a lot of things.”

Only last year, his dog Kaya died after a prolonged battle with cancer. “When we had our dog, I was not married, just a bachelor. She took me through that and getting married and having kids,” he stated.

After 30 years of practicing in a clinic, Dr. Liz Palmer decided to start a mobile veterinarian service specializing in end of life care for pets.  So when a pet goes from having good and bad days to bad and worse days, she can help with in-home euthanasia.

“When an animal gets very, very old, it can be very stressful to bring them to a clinic. They can get very nervous or confused,” she stated. “I hear an awful lot, that ‘I would prefer my animal to die naturally’…barring a heart attack in their sleep, I think dying naturally is overrated.”

Dr. Andersen says some people have such a tough time letting go, they often put off the inevitable. “If I hear regrets from people, it’s often because people feel like they waited a little bit too long and when they look back, they have this image of their animal suffering.”

After Dove decided to end his cat Scamper’s suffering, he took his buddy’s body to the Charlottesville Albemarle SPCA for cremation.

The SPCA offers private cremation for $130.00 and a variety of decorative tins for people to choose.  “You leave your animal in their care and a day or two later, they call you and tell you the ashes are ready,” Dove said.  Dove has Scamper’s picture and tin displayed at his home in memory of his beloved companion.

Paws and Remember is a company that offers everything from jewelry stamped with paw prints, key chains that carry ashes, to tiny caskets.  The Staunton company also provides cremation, most packages start at about $150.00 and go up from there.

But some pet owners can’t afford any extras.  Paws and Remember general manager Todd Dean says “If they don’t want their pet’s cremains back, then we will place them in one of these gardens here.”

The company has above ground crypts and a place where people can visit and leave flowers or pictures of their pets.

Since the death of Kaya, Dr. Andersen has adopted a new playmate for his other dog Boon. She’s an 8-week-old black lab named Ruby.  Dove did the same for his other little cat Krogie. He adopted a playful 3-year-old named Mocha from the SPCA. The new addition to the family gives Krogie a friend, but can never replace Scamper.

When he thinks back on the loss, Dove says “Love your animal as much and as often as you possibly can because you never know. I mean it almost doesn’t seem fair in a way that they don’t live longer than they do.”

For people who are struggling with the decision of whether to end their pet’s suffering, Dr. Andersen says the meaning of the word euthanize might help:  it means “good death”.

 

Knowing First Aid Can Minimize Pet’s Trauma

Our pets rely on us to take care of them when they’re sick or injured. But if we’re not prepared, panic and confusion might hinder our ability to act when they need us most. The best way to increase your chances of responding quickly and calmly to a pet emergency is to familiarize yourself with basic pet first-aid techniques.

“Properly applied first aid can minimize a pet’s trauma and even save its life until you are able to transport them to a veterinarian,” says Dr. Jim Clark of the Pet Emergency and Specialty Center of Marin. Clark and PESCM staff have treated animals for countless life-threatening conditions.

In an emergency situation, your first priority should always be to protect yourself. Before approaching an injured animal, carefully assess the scene to check for hazards (such as, electrical wires, traffic, unstable structures, etc.). If all looks clear, approach slowly and with caution. Any injured animal has the potential to bite.

An animal should be muzzled and properly restrained before any care is administered. If necessary, you can make a homemade muzzle on the spot using a piece of cloth. It may be dangerous to muzzle an animal that is coughing, vomiting, having trouble breathing or resisting. In this case, do not attempt treatment on your own.

Practice measuring vital signs on your healthy pet so that you become sensitive to changes that signal a medical emergency.

The heartbeat of a dog or cat can be felt by laying an animal on its right side and placing your hand over its chest, just behind the left elbow. Normal heart rates for dogs average 60 to 160 beats per minute, while cat heart rates average 160 to 220 beats per minute. A pulse also can be measured with your middle and index finger on the inner thigh, just below the wrist and just below the ankle.

You can measure an animal’s breathing rate by observing its sides to watch its chest expand. Normal dog breathing rates are 10 to 30 breaths per minute, while cat breathing rates average 20 to 30 breaths per minute.

While it may be difficult to practice taking your pet’s body temperature, note that temperatures from 100 to 104 degrees are considered an emergency.

If an animal has stopped breathing, knowing the ABC steps (airway, breathing and circulation) can mean the difference between life and death. If there is no breathing despite a clear airway, you will need to perform artificial respiration.

If there is no pulse, compressions alternating with breaths will be necessary.

Difficulty breathing, seizures, excessive bleeding, shock, poisoning, heatstroke and snake bites are some of the more obvious situations constituting an emergency. Learn what is normal for your pet so that you are able to recognize when something is abnormal.

Always have the phone number for your emergency veterinarian handy, too.

New Smartphone App Can Be Helpful in Saving the Life of Your Pet in a Poisoning

SamIam.jpgLorrie Shaw | Contributor to AnnArbor.com

These days, the ubiquitous smartphone keeps us connected and can help us get the information that we need quickly.

In my business, a smartphone is crucial tool in caring for animals, from being able to text, email or call clients to give daily updates, to verifying schedule changes and, most importantly, getting in touch immediately should an emergency happen.

I’ve mused about how we can put our smartphones to work as an effective tool helping with a sometimes difficult task by capturing a pet’s behavioral changes, lameness or symptoms that you can’t quite explain or mysteriously disappear when you step foot into the veterinarian’s office.

Handheld devices just became even more useful: A new app designed with your pet’s welfare in mind was released in late-March and could mean the difference between life and death for your animal companion.

 

Apple has made Pet Poison Help available for download and does two things: it offers information on hundreds of searchable household products and plants that have the propensity to be toxic to your critter, as well as guiding you through steps to take if your dog or cat is exposed to something that can harm them with direct dialing to the Pet Poison Helpline. The helpline is staffed by board-certified veterinary internal medicine and emergency critical care specialists and veterinary toxicologists.

The app, which costs .99 cents to download and is compatible with iPhone, iPod touch and iPad, is no substitute for a trip to your vet’s office or an emergency vet should something happen, but it can help get the ball rolling. The professionals staffing the helpline have special training to assist you and your own vet or emergency vet hospital (by dialoging directly with them) if your pet is critically ill from a potential poisoning.

Pet Obesity

As the number of Americans who are overweight has grown, studies show that the same statistics apply to our companion animals. About half of all dogs and cats in American homes are overweight or obese, up slightly from 2010, according to a recent study by the Association for Pet Obesity Prevention.

And although owners may think their pudgy dog or cat is cute, all that extra weight spells trouble the some 85 million U.S. pets who are considered overweight.

And many pet owners are finding that the extra pounds on a pudgy cat or dog can lead to severe secondary health problems. Just as diabetes, joint problems, and heart disease are more common in people who are obese, these diseases also are more common in overweight animals. The average cost of veterinary care for a diabetic dog or cat in 2011 was more than $900, according one pet insurance company. Treatment for arthritis and cruciate ligament tears in dogs, which can be caused by the strain of an overweight frame that weakens joints, cost pet owners an average of $2,000.

Last week, an interesting article the cost of pet obesity was published in the Wellness section of the New York Times. To read the complete article, entitled “Paying the Price of a Fat Pet,” click this link.

Do Cats with Hyperthyroidism in Cats Ever Go into Spontaneous Remission

Posted: 18 Apr 2012 06:36 AM PDT

From Dr. Mark Peterson on the Animal Endocrine Clinic Blog
Question:
Gracie, our 8-year old, spayed female DSH has just been diagnosed with hyperthyroidism, based on the finding of a high serum T4 value (12.4 μg/dl; reference range, 1-4.7 μg/dl). We only did her blood work in anticipation of a dental cleaning, and are shocked by this news. 

Gracie has no symptoms whatsoever of this disorder. She eats and drinks a normal amount; her diet has been mostly high quality, grain-free dry food (she never liked or ate canned until very recently, also grain-free).  She has shown slight weight loss, but only because she was overweight and we were controlling her intake — trying to get her to loose weight.  Her behavior and attitude are positive; no change from before. Her coat, skin, and eyes all fine. Hydration is fine. Digestion and bowels fine (no vomiting, no diarrhea). Just some bad breath (hence the dental). 

Our vet feels nothing upon palpation of her thyroid. If anything, she may have a slightly high heart rate (212 beats per minute taken at vet’s…possibly nerves), but her blood pressure was fine (averaged 128/77 out of 5 readings).

We had the T4 test run a second time at a different lab and it came back high again at 11.2 μg/dl.

My question to you is this….in your years of experience with hyperthyroidism, has there ever been an occasion when the T4 values have receded on their own, without medication or irradiation? I ask this because Gracie is so young and has no symptoms. 

I would not want to irradiate her thyroid if there is any possibility of this being a “passing phase” in her life. However, I am quite aware of the dangers and complications of hyperthyroidism, and do not want to play around with her health. With everything else so “normal,” I would be willing to wait a month or two and recheck her if you think there’s any hope in doing so. Are you aware of any current research indicating that T4 numbers can fluctuate in a young cat? More than any other factor, it is her young age that makes me question whether these T4 readings are permanent. 

My Response:
No, I’ve never seen a hyperthyroid cat go into remission. Cats with hyperthyroidism all have one or more benign thyroid nodules, generally benign tumors or adenomas (see Figure below). These thyroid tumors will not go away spontaneously once they have formed (1-4). The only way to cure this disease is by use of radioiodine (I-131) to irradiate the adenomatous thyroid nodule(s), or by use of surgery to remove the abnormal thyroid gland (1-6).

It’s sounds like you think that a cat of 8-year’s of age is too young to develop hyperthyroidism. But we do occasionally see cats as young as 6 years of age, and very rarely, even as young as a year or two (1-4,7).That all said, I’m bothered that your veterinarian is not able to palpate an enlarged thyroid tumor with a T4 value that is clearly quite high. You might want to have another veterinarian palpate Gracie’s neck to see if they can identify one or more thyroid nodules. If they cannot and the serum T4 remains high, it would be very useful to do thyroid scintigraphy (ie, a thyroid scan) to document the presence or absence of a thyroid tumor. Thyroid scintigraphy is the most sensitive diagnostic test we have to confirm the presence of hyperthyroidism in cats (8-10), and we use this procedure routinely in my practice.

You certainly could monitor the T4 value again in a month or two, especially since Gracie is stable. But it certainly does sound like she has hyperthyroidism and will need to be treated at some time in the near future.

Per an ASPCA Study, at Shelters, Dogs are Chosen for Looks and Cats for Behavior

Who can resist those big puppy-dog eyes, floppy ears and fluffy tail? In a new study to be released by the ASPCA, “physical appearance” is the top reason given for picking a particular puppy at an animal shelter.

With cats, it’s a different story: “Behavior with people” was what convinced most adopters to choose a particular adult cat.

The research, conducted by the animal-advocacy organization from January through May of 2011, involved five shelters across the country. About 1,500 adopters filled out questionnaires explaining how they knew the cat or dog was “the one.”

By understanding why people choose the pets they do, the ASPCA hopes to increase adoption rates and ensure adopters go home with a perfect match. It’s particularly useful for shelter workers to know that appearance is often a deciding factor. They can then counsel adopters about behavior and other traits that might be overlooked.

“As an animal behaviorist, it was interesting to get inside the human animal’s head,” says Emily Weiss, vice president of shelter research and development with the ASPCA.

The study supported findings from previous research showing that animals that approach the front of the cage when a visitor nears have a much greater chance of being placed in a new home. In the new study, many of the adopters who were asked, “What did this pet do when you first met him/her?” specified a social interaction, such as an approach, a meow, a lick or even jumping on the visitor.

“That interaction is important for the human animal—not just entertainment, but in choosing their next friend,” Dr. Weiss says.
