This problem is an unusual behavior issue as compared to a urination issue and has been known to perplex most veterinarians and behaviorists.  Our team has lectured nationally and internationally on this “blind spot” issue to veterinarians, shelter workers, and cat advocates from China to Chicago.

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.

Frequently Asked Questions

All cat behavior solutions must take into consideration feline instincts and their evolutionary biology. The clinic has exclusive rights to Mieshelle Nagelschneider’s proprietary Cat Whisperer™ consulting, easy-to-implement C.A.T. Plan™ positive behavior modification, the most effective, comprehensive, and up-to-date system for curing any cat behavior problem.

Because every cat and environment is different, the plan allows for customized behavior techniques and environmental changes when needed – because cat behavior is not one-size-fits-all. Mieshelle has spent 20 years developing a method so effective that when clients follow it, their success rate is well over 90% (even higher for the most common issues).

Her science-based cat behavior book, The Cat Whisperer, has been featured in the New York Times and a best-seller on Amazon and published in 4 languages (Random House Publishing with co-writer Cameron Powell).

For cat behaviorists seeking certification, her book is a required curriculum by a number of cat behaviorist certifying organizations.

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

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. We often misunderstand cat behaviors. 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.

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