Schedule with Our Veterinarian and Oxford-trained New York Times Acclaimed Cat Behavior Science Author and Certified Cat Behaviorist Mieshelle Nagelschneider



Since 1999 the Clinic Has Been Solving Cat Behavior Issues in Over 30 countries by Scientifically Observing and Analyzing Behavior from a Behavioral Cognitive, Ethological, and Feline Evolutionary Point of View.

One of the few cat behaviorists and founder of the first cat-only behavior clinic, Mieshelle Nagelschneider studied animal behavior at Oxford University and cat behavior specifically through the University of Edinburgh (Royal School of Veterinary Studies). She is the award-winning 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. 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.

Recipient of the Golden Purr Award for her contribution to cat behavior, you can learn more about her other animal studies including her experience at Harvard University on our Animal Behavior Study Page. Our Veterinarian Dr. Jim Shultz performs local in-home consultations only.

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.

Watch her on Today Show, the Hallmark Channel, NBC Dateline, and National Geographic documentaries, shows, and published works as the expert on the 37 wildcat species including the domestic cat and wildcat hybrids.

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.”

2019 Cat Testimonials:  Thanks to your cat behaviorist, we now have a urine-free cat family just like she said we would.  Our home no longer smells like cat urine and the added bonus is that our cats are so much happier.  The information provided is no where on the internet.  The consultation program was very worth our time and investment and we feel so lucky to have worked with Mieshelle.   Regards, The Taylor Cat Family, Miami, Florida

December:  Well,  I can’t believe it took just 3 days, but it was that easy.  We DID NOT have to add extra litter boxes either.  Mieshelle is brilliant and saw the problems right away.  It’s week 7 and not one accident outside the box.  Claudine has begun playing again with her toys and she actually sits next to Augustus now.  This is unheard of and I can’t thank you enough.   All the best, One grateful and enlightened cat owner.  Paula S.  Orlando, Florida

November:  I considered myself a very savvy cat owner having owned multiple cats my entire life, but I have learned so much from Mieshelle, your cat behaviorist.  When we rescued the feral cats from our Florida golf course, we had no idea what we were in for.  The urine almost ruined our home and the cats fighting almost ended our marriage.  Mieshelle became the light in the very small world of cat behavior knowledge available to cat owners.  We have recommended your practice to our Florida veterinarian and we will contact you after we return from our vacation to schedule our last call.  Thank you for all that you do.  Mary S. – Tampa, Florida
