The Cat Behavior Clinic is a unique organization devoted to both researching and solving cat behavior problems. Unfortunately, there is no other organization doing so today. The clinic opened in 1999 and now serves satisfied clients all over the world (see our Rave Reviews). The Cat Behavior Clinic was founded by Mieshelle Nagelschneider, a nationally known veterinarian-referred cat behaviorist who studied animal behavior at Harvard University and has dedicated 20 years to consulting with cat owners around the world to solve their cats’ behavior problems. She and her team have provided Cat Whisperer® behavioral consulting services to thousands of cats worldwide.



The Cat Behavior Clinic has exclusive rights to Mieshelle’s proprietary C.A.T. Plan™ treatment system, the most effective, comprehensive, and up-to-date system for curing any cat behavior problem. Mieshelle has spent 20 years developing a method so effective that clients who follows it are typically seeing a success rate of more than a 90%. Success rates are even higher for issues that have not been chronic and habituated over years.
Through word-of-mouth and satisfied clients as well as our work with wild cat sanctuaries, veterinary practices, and shelters, The Cat Behavior Clinic has become renowned in the field and especially at solving the so-called “unfixable” behavior issue. See our Media Room for the 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 our behaviorists have successfully applied a method consisting of compassionate awareness and three-part behavior modification 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. We use a 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 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.
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 colony behavior dynamics.
