What’s a Cat Behaviorist?

dog's paw in person's hand - animal rescue, shelter

A cat behaviorist is someone who specializes in understanding cat behavior… what makes us tick!

In recent years as more people have brought cats into their homes, there’s been a growing interest in cat behavior and helping people resolve problems with their cats.

Behaviorists deal with problems like cats fighting, scratching, biting, and peeing outside the litter box.

Television shows like “My Cat From Hell” and “Cats 101” have brought attention to the need for behaviorists and has been helpful for many people.

You can find people advertising themselves as cat psychology professionals, cat whisperers, trainers, feline or animal behaviorists, cat behavior consultants, or experts.

There are also veterinary feline behaviorists who are experts in both medical and behavioral problems.

When Do I Need a Behavior Expert?

helping hand up

You should consider hiring a behavior expert when you need help if you can’t figure out how to deal with problems like inappropriate peeing outside the litterbox, scratching, fear, fighting, biting, cats not gettign along.

There’s information available (yes, even at this site!) to help you know what to do, but there are times when you need extra help.

How Do I Know Who’s Legitimate?

Since anyone can put up a website and claim to be a cat expert, you should know what to look for when hiring someone.

There are currently no regulations or licensing requirements in the U.S. that govern who can call themselves a cat behavior expert.

You’ll discover quickly that cat behaviorists aren’t on every corner, but they can usually work with you by video conference if the distance is too great to travel.

Some of them give priority to urgent situations such as a cat peeing outside the litter box or fighting.

Main Considerations

checklist on clipboard

There are 4 main things to consider when looking for a behaviorist…

  • Behavior adjustment methods – positive association only, no punishment
  • Reputation
  • Consultation costs – including if any travel is involved
  • Level of education/credentials

Behavior Adjustment Methods

What methods does the person use when dealing with cats? What is the basic philosophy of their approach?

Is it all positive reinforcement methods that build trust between you and your cat?… Yes!

Or is punishment like swatting or spraying with water part of their approach?… No!

Be sure you understand any costs, including beginning and follow-up consultations, travel and anything else involved.

Don’t be afraid to ask questions.

Talk to the staff at vet offices to discover more about the expert’s reputation and abilities.

Ask for references you can contact directly and check Yelp, Nextdoor, and other review sites online.

Be sure they work primarily with cats, not just animals in general.

One thing to watch out for is anyone advertising “guaranteed results” or something similar… nothing is guaranteed with cats!


diploma, graduation cap, hat

Credentials (diplomas, certifications, or titles) assure you that the expert has achieved a high level of education and expertise in their field.

In a newer field like cat behavior there are respected pioneers and well-known behaviorists that have learned totally through years of experience and observation.

They have, in fact, developed concepts and techniques that are now taught in behavior courses.

These experts are typically veterinarians or PhD’s who specialize in cat or animal behavior, although there are a few exceptions such as Jackson Galaxy.

Others have taken courses and are certified and credentialed through respected organizations.

Still others have taken classes or simply decided they know all about cat behavior from their own cats and want to make this a career.

You’ll have to decide if credentials, experience or a combination is most important for you.

The advantage of working with people certified by these organizations is that you know they’ve attained a certain level of education and skill to earn certification.

Those who have specific credentials are…

  • Certified Applied Animal Behaviorists
  • Certified Animal Behavior Consultants
What’s a Board-Certified Veterinary Cat Behaviorist?
vet office, behaviorist, specialist

A “Board-Certified Veterinary Behaviorist (DACVB)” is certified as a Diplomate through the “American College of Veterinary Behaviorists” (the certifying board).

(Veterinary professional organizations are often called “colleges”, which is different from the educational institutions most people associate with the word.)

This type of behaviorist has persevered through 4 years of university study to receive a bachelor’s degree, then 4 years of vet school to become a DVM, then additional years (usually 3) in a specialty, in this case cat or animal behavior.

“Veterinarians are uniquely qualified to understand the interplay between medical problems and behavioral issues.

And unlike all other animal behaviorists, they can prescribe drugs like anti-anxiety medications to take the edge off impulses that lead to problem behaviors, all while teaching owners behavioral tricks for readjusting their pets.”1What Credentials Does the Animal Behaviorist Have? 4 types of specialists to choose from.” by estaff, Catnip Newsletter, Tufts University, Cummings School of Veterinary Medicine, Published: September 16, 2019, Updated: September 18, 2020

What’s a Certified Applied Animal Behaviorist?

A “Certified Applied Animal Behaviorist” is a type of vet behaviorist certified through the Animal Behavior Society.

The requirements for certification are the same as for Board-Certified Vet Behaviorists, but they follow a different path to get certified.

man holding kitten - veterinary medicine

As with Board-Certified behaviorists, these vets go through 4-year university programs, then 4-year vet school for a DVM degree, then do advanced training in animal behavior.

They must pass difficult and thorough oral and written exams, have supervised hands-on animal experience, and meet other requirements of the Animal Behavior Society.

What’s a Certified Animal Behavior Consultant?
various pets. animals

A “Certified Animal Behavior Consultant” is someone pursuing a career in any type of animal behavior who is certified through the International Association of Animal Behavior Consultants (“IAABC”).

A Certified Cat Behavior Consultant has completed training and testing specifically for the feline species.

Those who are certified by the IAABC have gone through a rigorous training program and testing to be sure they have a good foundation of knowledge about animal behavior.

3 kittens, one with eyes closed

The IAABC is an organization in over 70 countries around the world with different levels of membership, depending on the skill levels and experience of members.

Its purpose is to support and promote behavior professionals at every level and stage of their career.

The IAABC also works with “other organizations and governments to codify the standards of practice of animal training, promote animal training as a recognized profession, and to support industry regulation that forwards the humane practice of animal training.”2 International Association of Animal Behavior Consultants (IAABC)

“All our members are bound by the Joint Standards of Practice and Code of Ethics, which include a commitment to using LIMA, the Least Intrusive, Minimally Aversive effective intervention when working with animals and their human companions.”3 International Association of Animal Behavior Consultants (IAABC)

How Do I Find a Cat Behaviorist?

Start by discussing the situation with your vet who might be able to recommend a specific expert for your individual needs.

If you’re interested in working with someone not a member of an organization, ask questions about their qualifications and check references carefully.

Be sure they use positive reinforcement methods and specialize in cats, not just general animal behavior.

Since many of these experts do video conferences you don’t have to be located near them to get their help.

Probably the safest way to find someone is through one of these reputable organizations.

Well-Known Behaviorists

woman holding kitten upright

There are some cat behavior experts who are well-known in the cat world and beyond.

One thing they all have in common is the desire to keep cats in homes and out of shelters.

The more people understand about their cats and learn how to encourage the behavior they want, the less likely the cats will end up in shelters, euthanized, or on the streets.

Here are a few well-known experts… (this is not an exhaustive list).

Some links below are for Amazon… I make a small commission from them.

“’All people who like animals have an interest in animal behavior, but they don’t understand how to put what an animal does into context,’ [Dr.] Beaver said.

Sources used on this website are either primary or secondary.

Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.

Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.

However, sometimes they refer to primary sources.

When I use secondary sources, most are those with some authority, such as veterinarian or cat behaviorist books and articles.
