Vital Components to Change a Cat’s Behavior with Cat Behavior Consulting

Like it or not, working with a cat behaviorist that has formal study in animal behavior 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 and that have helped thousands of cats and their owners since 1999.  With litter box elimination issues, urine-marking, excessive meowing, inter-cat social and aggression issues, expect to receive an involved behavior plan to change your cat’s behavior long term.

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

Blue Double Quotations | Mieshelle Nagelschneider | Cat Behaviorist


“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.”

“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. 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.

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.

By the time cat owners consult with Mieshelle, 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, the clinic offers either a 4 week or 8 week program after a consultation for continued support.   Mieshelle is 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 she conducts.

Coaching Cat Owners for Cat Behavior Results That Last

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.
