Cat Behaviorist Organizations and Affiliations
Award-winning cat behaviorist and cat science author (Random House and National Geographic), Mieshelle was one of the first certified cat behaviorists in the United States and has been a past or long time member of cat behavior organizations like The Animal Behavior Society, Cat Behavior Counselors (Certified), The International Association of Animal Behavior Counselors (past Associate Certified Cat Behavior Counselor Cat Division) among others. There are still only a handful of cat behaviorists as compared to dogs trainers and veterinary behaviorists. Cats are still very underserved in the behavior category when it comes to cat care. With over 40,000 hours of conducting feline consultations and the first cat-only behaviorist practice in the United States, Mieshelle is considered the pioneer of the cat behavior specialty and one of only three notable cat behaviorists (Wikipedia) in the United States.

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.

In her book The Cat Whisperer, 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.”—Jordan Carlton Schaul, Ph.D., contributing editor, National Geographic, and curator, Orange County Zoo

What Our Colleagues Say About Cat Trainer 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
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 Therapist Need to Come to My Home?
Feline therapy is very different from canine therapy 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 consultation and follow-up is offered over the course of several weeks for all of our consultations programs.
