cat sit on man's lop Cats are adorable and fun pets that typically have their own set of unique quirks. They can bring smiles to faces, but sometimes, they might start displaying behaviors that leave us feeling puzzled or even concerned. Oftentimes, cats confuse humans because they “speak” a different language. They’re actually excellent communicators, but humans will often misread or completely miss their body language and cues. This is where a cat behaviorist can step in to help. If you’re curious about how your cat communicates with you or are experiencing difficulties with unwanted behaviors, make sure to connect with a reputable cat behaviorist. Many cat behaviorists are passionate about keeping cats away from animal shelters, so they’re more than willing to connect with cat owners to eliminate destructive behaviors. They offer consultation services to provide education and plans for owners with cats that display challenging behaviors, such as aggression, spraying, and scratching.

What Is a Cat Behaviorist?

A cat behaviorist is someone who studies cat behaviors. Some cat behaviorists have certifications with reputable organizations, such as the International Association of Animal Behavior Consultants (IAABC) and Canine and Feline Behaviour Association (CFBA).

However, certifications alone don’t guarantee that a cat behaviorist has effective practices and programs. Many famous cat behaviorists, such as Pam Johnson-Bennett and Jackson Galaxy, became experts through hands-on experience and personal research. A good cat behaviorist will assess a cat’s history, temperament, and home environment to determine the root cause of cat behaviors.

If you live with a cat with challenging behaviors, consider working with a reputable cat behaviorist. Many cats share common challenging behaviors, and a good cat behaviorist will be able to accurately determine the cause of these behaviors.
