Why The Cat Behavior Clinic is Unique

The Cat Behavior Clinic is a unique organization devoted to both researching and solving cat behavior problems, and unlike many cat behavior services, we have both a licensed veterinarians and cat behaviorists. Many cats we work with have both medical and behavioral issues at play.  The clinic opened in 1999 (prior to that is was Help Your Cat Behavior Consulting in 1990) and now serves satisfied clients all over the world conducting phone or Zoom video behavior consultations. The Cat Behavior Clinic is a nationally known veterinarian-referred cat behavior counselor practice.  Please visit our Cat Behaviorist homepage.

Mieshelle is a member of The Feline Practitioners of America, Association of Animal Behavior Professionals, Cat Behavior Counselors (Certified), and past associate certified cat counselor of the International Association of Animal Behavior Counselors (2007).  She has dedicated 36 years to consulting with cat owners around the world to solve their cats’ behavior problems. The clinic performs behavior data studies and has provided science-based Cat Whisperer™ behavioral consulting services to thousands of cats worldwide.

Published in 4 languages, Mieshelle’s New York Times Acclaimed Cat Behavior Science Book is the Recipient of The Golden Purr Award.

The C.A.T Behavior Plan

The Cat Behavior Clinic has exclusive rights to Mieshelle’s proprietary C.A.T. Plan™ Cat Behavior Wellness Program, the most effective, comprehensive, and up-to-date cat behavior wellness program for curing the most common cat behavior problems. Mieshelle has spent 36 years developing a method so effective that clients who follows it are typically seeing a success rate of more than 90%.  Success rates are even higher for issues that have not been chronic and habituated over years.

Achieving the impossible

Through word-of-mouth and satisfied clients as well as our work with wild cat sanctuaries, national and international humane societies/SPCA’s, veterinary practices, and national and international shelters (including Best Friend’s Animal Society), The Cat Behavior Clinic has become renowned in the field and especially at solving the so-called “unfixable” cat behavior issue.  See our  Media Room for national and international media recognition.

Many people will tell you that it’s impossible to train or otherwise change the behavior of a cat.  But over the last two decades the clinic has successfully applied a method consisting of compassionate awareness (specifically, your cat being a descendant of the African wildcat) and a three-part behavior modification cat behavior wellness program to help resolve the unwanted behaviors of thousands of cats, and we’re here to show cat lovers that cats’ behavior can be reliably and consistently changed for the better.  And we’ll show you exactly how using the uniquely effective three-stage method of solving every one of the seven major cat behavior problems.

We deal with the most extreme behavior issues in cats, as well as everyday problems like aggression, spraying, and litter box issues—problems that cause millions of cats to be surrendered to shelters every year.  In the U.S. there are 88 million households that include one or more cats and virtually every one of those cat owners has at some point dealt with feline behavior that drove them nuts.  And the truth is, almost every cat behavior problem is solvable.  If a cat is placed in an environment that falls in line with his natural cat instincts and is conducive to his happiness, everything will fall into place (yes, even the way you desire).  Otherwise, his unwanted behaviors (which are instinctual) will surface.  It all depends on the surrounding circumstances for each cat.

Our Philosophy

Cats are not like dogs. They are also not like humans. All cat behavior consulting has to start with this awareness. That’s because nearly all failed efforts to modify cats’ behavior assume that cat psychology is like dog psychology (or worse, like human psychology). These efforts are doomed to fail because they are based on ignorance of the uniqueness of individual cats and instinctual colony behavior dynamics.
