Member of the Cambridge Center for Behavior Studies and the Animal Behavior Society, Mieshelle Nagelschneider, and Dr. Jim R. Shultz Jr. DVM enjoy the most difficult cat behavior consulting cases that have been deemed “unfixable”.

Like it or not, working with a real behaviorist that has formal study in animal behavior like at The Cat Behavior Clinic,  is a vital component in solving any cat behavior issue.  Without a behavior plan that is 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. Mieshelle can solve your cat’s behavior issues with a behavior plan designed for your cat(s) that include the latest scientific research and advanced techniques (we guarantee found only here) that have helped thousands of cats and their owners since 1999. Litter box elimination issues, urine marking, excessive meowing, inter-cat social and aggression issues, are her specialty.

From Mieshelle “I have been studying cats for over three decades — thousands of cats, in thousands of different environments. I have helped more cats and more cat owners — nationwide, in person or on the phone — with hundreds of client and vet testimonials since 1999. I truly believe The Cat behavior Clinic will be your final stop for solutions with behavior techniques found only here from our latest research and my study of animal cognition at Harvard University.


After cat owners have tried one cat behaviorist after another (and they’re aren’t many out there to begin with), after they’ve talked to vets whose specialty isn’t actually feline behavior, even after the cat owners have found themselves in the parking lot of their local humane society – they call me.  And time after time, I have come through for them, just as I will for you. Please read our Rave Reviews! (from 1999 -2012).  I’m proud to say that I have been consulting with cat owner’s for almost 15 years.  The litter box consultation alone I have conducted 7,000 times from Greece to Manhattan.”  This is the most common behavior issue in cats.

Mieshelle Nagelschneider, C.A.T. Counselor, is a member of Cambridge Center for Behavior Studies,  and past Associate Certified member of the IAABC, and a member of both the Animal Behavior Society and the Association of Animal Behavior Professionals. Her most recent study of animal behavior was at Harvard University, with a focus on animal cognition. The information and help you receive from Mieshelle is up-to-date on the latest trends of animal psychology — and unlike anything you’ve read on the internet, popular books, or advice received from your vet.  Random House Publishing (and other major publishers)  covering over 80 countries commissioned Mieshelle to write a book on her science-based methods.


You DON’T Have to Give Up Your Cats — Not Even Bengals Thank you Mieshelle for helping us solve the behavior problem with our two Bengals! It was hard to believe it was so simple for what seemed like a complex issue, but you were right and we have had no issues since our consult. I can’t believe I was thinking about re-homing. You offer a great service and I just hope more cat owners will learn of your service. You definitely figured out what even our vet couldn’t (he is referring you now too by the way).   Steve and Diane, Miami, Florida– 2002


“Mieshelle, I can’t thank you enough for all the work that you did for us! I am so glad I called you. We all live in peace and harmony again because your methods work!! I will recommend you to everyone I know. Your service is invaluable.”
Heather K., Portland, Oregon


“I can’t believe how simple it was,” pet owners tell me once we’ve corrected their cat’s problem. “Everyone else was making it seem so complicated and hopeless.”

Some things are complicated. But not everything needs to be. Here’s another comment I hear very often: “Now I finally understand my cat’s psychology.” And because I make a point of educating my human clients, they are better able to handle future problems on their own or at least not unknowingly create a new one.

Who else wants a great relationship with their cat?

Feline Behavior Problems Treated in Our Two Consultation Process:


With a detailed case history and behavior summary of each cat, the appropriate behavior modification and retraining techniques can be implemented into your cat’s daily life. It’s important to note that not only will the treatment plan include your cat with the misbehavior, but other pets and people directly involved in the environment. Many times, owners and other pets in the household could be contributing to, reinforcing, or triggering the undesired behavior. For the treatment plan to be most effective, it’s important that we take the time to look at every aspect of your cat’s life.

Finding out what is triggering your cat’s misbehavior is the first goal. The problem will often subside merely after removing the trigger. However, it is also common for a habit to have formed and the negative behavior to continue even after the trigger is removed. If the cause for the misbehavior is not found, we will treat with behavior modification techniques and new, healthy habits to be developed through retraining.

Coaching Cat Owners for Results That Last

By the time cat owners consult with me, they have tried everything and are very discouraged. Often the relationship between owner and cat is tense and has deteriorated to the degree where the environment is not conducive to the cat’s happiness. This alone is enough to cause the existing behavior problem to worsen, or yet another one to surface. That’s why, for  2 months after a consultation, I’m here for the cat owner to ensure they have the best results with the behavior plan. Cat behavior is not one-size-fits-all and components of a behavior plan may need adjustment along the way.  We offer phone follow-ups if a cat owner needs help along the way. Also, without understanding the cat psyche, owners may be making choices that are creating a stressful environment which can lead to many of the most common feline behavior issues.  This is why preventative maintenance is part of every behavior consultation I conduct.

Are you ready for a permanent solution? Your cat is wondering what you’re waiting for!
