There is simply no cat behavior problem we have not helped our clients solve many times — or that we cannot help you to solve now.  Our licensed veterinary and cat behaviorist team provide excellent and comprehensive cat behavior care by applying the sciences of genetics, animal psychology, biology, physiology, and feline learning and memory to effectively correct a cat’s behavior – all with a Zoom video call or in-person in select areas.  This is why we have more cat owners purring than anyone (hundreds of testimonials since 1999 here).

Do You Need to Rule Out Health Issues to Receive Behavioral Help for Your Cat? Short Answer – No

You do not need to rule out a health issue with your veterinarian to receive behavior help for your cat. In fact, cats that do have chronic health issues can still be helped with effective therapies behaviorally. Do we recommend your cat have routine exams by your vet? Yes. In fact, we recommend this occurs once yearly, but there is no reason to postpone behavioral help for your cat (or cats) while waiting for a vet appointment or even if they are found to have a health issue. Medical and behavioral issues can overlap. Chronic urinary health condition cats are not a lost cause and can be helped behaviorally by our team so they will urinate in the litter box 100% of the time. We have helped thousands of cat owners for over two decades and in over 30 countries by phone or video solve their cat’s behavior issues. Recipient of the Golden Purr Award and Gambol Myfoodie Award for Behavior and Cat Nutrition for her contribution to cat behavior (her scholarly-cited book is used to certify cat “experts” and veterinarians you see today around the world), you can learn more about Mieshelle’s animal behavior study and experience at Oxford University and Harvard University here. Her 2-time Academy Award-winning cat behavior show, My Cat from Hell, is the most watched cat behavior show in the world with over 1 billion viewers. The clinic is also the newly appointed cat nutrition research and develop experts for the largest cat food company and manufacturer in the world to help cats truly thrive behaviorally and nutritionally.
