For Over Two Decades Solving Thousands of Cat Urination, Defecation, Marking and Aggression Issues in Over 30 Countries. The Clinic Scientifically Observes and Analyzes Cat Behavior from a Behavioral Cognitive, Ethological, and Feline Evolutionary Point of View.

OXFORD UNIVERSITY was Mieshelle Nagleschneider's most recent study of animal behavior. She is the founder of the first cat-only behavior clinic practice in the United States. Her other animal behavior studies include cat behavior specifically through the University of Edinburgh (Royal School of Veterinary Studies). You can learn more about her other animal studies including Harvard University on our Animal Behavior Study Page.

Mieshelle is a cat behaviorist for National Geographic television shows and published works and you can also watch her on the Today Show, Hallmark Channel, NBC Dateline, and MTV. Since 1999, her in-depth applied scientific analysis of the behavior and evolutionary biology of the cat has enabled her to help thousands of cat owners over two decades and in 30 different countries, solve their cat's behavior issues.

She is the award-winning international author of New York Times acclaimed feline behavior science book published in 4 languages by Random House Publishing and a long time cat behavior expert for National Geographic documentaries and published works on cat behavior and the 37 species of wildcats including the domestic cat and wildcat hybrids.

Mieshelle coined the term and was the first "Cat Behaviorist" and "Feline Behavioral Scientist" in the United States and is the recipient of the Golden Purr Award for her contribution to cat behavior. Our Veterinarian Dr. Jim Shultz performs local in-home consultations also.

To achieve behavior results that are lasting, it’s necessary to work with an experienced cat behaviorist, but most importantly, one with formal university study in animal behavior that can apply the sciences of gene-encoded behavior, animal psychology, feline evolutionary biology and physiology, to effectively correct a cat’s behavior.

Mieshelle travels the globe from Australia to the Philippines lecturing at the international level to veterinarians and shelter workers to help them better help cat owners for over two decades solving “unfixable” behavior issues. She goes beyond the obvious facts about cat behavior and offers intelligent and proven solutions. Cat owners receive systematic behavior plans and guidance based on feline evolutionary biology. She is world-renowned for her global leadership in cat behavior education and crossing the conventional boundaries of the cat behavior specialty.

Cats are still the most misunderstood companion animal that are at the greatest risk. The hundreds of vets that the clinic works with and who refer cats to us often say, as will vet behaviorists, "we still don't know what to do with cats". Dr. Jordan Carlton Schaul, Ph.D., contributing editor, National Geographic, and past curator, Orange County Zoo “The reason people are so mesmerized by house cats is because they are truly miniature versions of lions, tigers, and leopards. In her book, Mieshelle Nagelschneider explains the behavior of the house cat in an unprecedented and most accessible way, offering unique insight into the often misunderstood companion animal that is as wild as we have become civilized.”

For over two decades, California cat behaviorist Mieshelle Nagelschneider, has conducted several thousand cat behavior consultations in over thirty countries.

Cat behavior issues like urination, defecation, aggression and other cat behavior issues are very solvable. Taking into consideration feline evolutionary biology and your cat’s gene encoded behavior (instincts and fixed action patterns) is just one of several components that must be a part of a successful behavior plan that has lasting results.  To achieve this, it’s necessary to work with an experienced cat behaviorist, but most importantly, one with formal study in animal behavior that can apply the sciences of genetics, animal psychology, biology, physiology, learning and memory to effectively correct a cat’s behavior.
