Solving 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.”

About Cat Behaviorist
Dr. Jim Shultz with a furry patient.

Without a behavior plan that’s carefully created drawing from current research on cat behavior to appropriately address all the critical components and factors of a presenting behavior, is like trying to conduct a symphony without sight or sound. Behavior plans that completely eliminate a cat behavior issue are not one-size-fits-all. 

After your consultation should any changes or additions need applied to your cat’s behavior plan, we are here for additional correspondence. Cats are not all the same and can respond differently to various techniques and a behavior plan should respond and reflect your cat’s uniqueness.

What Our Colleagues Say About Cat Whisperer™ and Feline Expert, Mieshelle Nagelschneider: 

Love is born of mystery, and our cats are mysterious and loved in equal measure. But sometimes the greatest blessing of all is a bit of light thrown into a dark place. Mieshelle Nagelschneider holds that light. Allow her to share it with you.”– Gwen Cooper Author, Homer’s Odyssey: A Fearless Feline Tale, of Life With a Blind Wonder Cat (Random House), New York, NY

Veterinarian: “Over the course of many years, Mieshelle has developed and refined her unique ability to think like a cat. On numerous occasions I have witnessed the life-changing benefits Mieshelle’s techniques can bring to cats and their sometimes very frustrated owners.” – Veterinarian, Dr. James R. Shultz DVM, Portland, Oregon

Cat Behavior Veterinarian Referral from Dr. Lisa Berger DVM: “Despite all the disruptions, there have been no incidents of urination on the bed or the couch, and neither have been covered by plastic all week!” – Juanita H. Portland, Oregon

“Literally our problem seems to be solved ‘overnight’ and we are very optimistic that this will stay: we even see her using the cat litter box; she buries her urine, and seems to be very comfortable. This is unbelievable, Mieshelle. We are very thankful for your precious help and knowledge.” – Best regards, Andrea & David M. Chicago, Illinois

You have the African wildcat, your domestic cat’s ancestor, to thank for many of your cat’s “unwanted” cat behaviors. Learn more about this during your consultation to better understand and help your cat and solve its behavior issues.  Oftentimes, cat behaviors are severely misunderstood.  Once cat owners understand their cat instincts and biology, they can better understand why the behavior strategies work so well and can better apply them.

Does a Cat Behaviorist Need to Come to My Home?

Definitely not.  Feline behavior is very different from canine behavior and the approach to changing a cat’s behavior is even more different.  Cats do not display obedience problems like dogs.  Therefore, the kind of help you need is not focused on physical or verbal behavior modification strategies like you’d directly apply to a dog with a dog trainer present.  All cat behaviorists generally conduct consultations by phone or video Skype.  Our behavior plans are specific to cats and still allow for the natural feline instincts, but when and where you want them displayed.  The behavior plan is covered during the phone or video Skype Consultation and follow-up is offered over the course of several weeks for all of our consultations programs.
