National Geographic Cat Expert And New York Times Acclaimed Cat Behavior Science Author Scientifically Observes and Analyzes Cat Behavior From a Behavioral Cognitive, Ethological, and Feline Evolutionary Point of View.

OXFORD University, The Royal School of Veterinary Studies at The University of Edinburgh was Certified Cat Behaviorist Mieshelle Nagelschneider's most recent study of animal behavior. You can learn more about her additional animal behavior studies including Harvard University on our Animal Behavior Study Page. She is world-renowned for her global leadership in cat behavior education and crossing the conventional boundaries of the cat behavior specialty.

Analyzing cat behavior and solving their issues in over 30 countries, Mieshelle is the founder of the first cat-only behavior clinic practice in the United States. Since 1999, her applied scientific analysis of the behavior and evolutionary biology of the cat has enabled her to help thousands of cat owners over two decades, solve their cat's behavior issues. Our veterinary team is also an integral part of helping cat owners and offer vet-to-vet consulting. Dr. Jim Shultz performs local in-home consults.

Mieshelle has been the cat behaviorist and long time research expert for National Geographic television shows, published works and documentaries on cat behavior and the 37 species of wildcats including the domestic cat and wildcat hybrids. You can also watch her on the Today Show, Hallmark Channel, NBC Dateline, and MTV. She is an award-winning international author of New York Times acclaimed feline behavior science book published in 4 languages by Random House Publishing.

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.

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 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.

Cats are still the most misunderstood companion animal that are at the greatest risk. The hundreds of vets the clinic works with each year 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.”
