Certified Cat Behaviorist, Mieshelle Nagelschneider, is here to solve your cat’s behavior issue(s). Like it or not, working with a cat behaviorist that is not only certified, but has formal education and experiential work in cat behavior, is vital in solving any cat behavior issue (The Cat Behavior Clinic has all of these). 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, which is why we are here for additional correspondence after your consultation should any changes or additions need applied to your cat’s behavior plan. 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.

TRUSTED SOLUTIONS: Best of all, the Clinic has exclusive rights to Mieshelle Nagelschneider’s proprietary, 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).

Hiring a Cat Behaviorist?  Should You Hire a Cat Behaviorist like Mieshelle Nagelschneider or Jackson Galaxy?

“The reason people are so mesmerized by house cats is because they are truly miniature versions of lions, tigers, and leopards. Mieshelle explains in an unprecedented and a most accessible way, the behavior of the house cat, with her unique insight into the often misunderstood companion animal that is as wild as we have become civilized.” Jordan Carlton Schaul, PhD — Contributing Editor, National Geographic Society, Zoological Curator (Alaska Wildlife Conservation Center and Orange County Zoo), Affiliate Professor (University of Alaska) and Proprietor of Animal Trainer Dude™, Los Angeles, California

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 Heimann 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.
