Aggressive Cat Behavior is Solvable
Experienced and Licensed Doctor & Certified Cat Behaviorist (Studies at Harvard and Oxford University) and Pioneers of the “Cat Behaviorist” Specialty
Aggressive cat behavior is among the most challenging to owners. “I have a very very very angry cat,” some clients tell us. “I have a mean cat that is trying to spite me” say others, or “a cat that gets mad for no reason.” But whether you have a scratching cat or a biting cat, an “attack cat” or your cat attacks a baby, we can help. The first key is to determine what kind of aggression your cat is displaying. Almost all types of feline aggression are normal, and all can be modified non-aversively, with the right expertise. If your cat is attacking you or other humans, or you want to learn how to prevent misplaced aggression (the most common form of aggression), read on. (is your cat fighting other cats?)
Unlike other “cat behaviorist” or “cat counselor” services, our veterinary behavioral services are covered by most pet health insurance plans.
Solving Cat Aggression Issues Scientifically
To achieve behavior results that are lasting, it’s necessary to work with an experienced and certified cat behaviorist (this is very different than a trainer), but most importantly, one with formal study on the wild felid and in animal psychology that can effectively apply the sciences of genetics, animal psychology, biology, physiology, learning and memory to effectively eliminate your cat’s aggression issue.

Mieshelle’s Cat Behavior Science Book is Used as Text Book Curriculum to Certify Other Cat Behaviorists and Help Them Understand Aggressive Behavior in Cats.
Award-winning Cat Behaviorist and New York Times Acclaimed International Feline Behavior Science Author, Mieshelle Nagelschneider studied animal behavior at Oxford University, and The Royal School of Veterinary Studies, University of Edinburgh. Her Harvard studies have also enabled her to help cat owners understand their cat’s behavior from a scientific point of view instead of an anthropomorphic one.

Understanding Wild Felids and Cat Aggression: A Very Solvable Issue in the Domestic Cat
Read our clients’ 350 Solved Feline Behavior Case Studies and Client Testimonials and see why the Clinic is a smart choice for solving an aggression behavior issue now. The first cats exclusively behavior practice in the United States, The Cat Behavior Clinic is also the home of The Nagelschneider Method™, based on wild felid instinctual behavior and a way of reintroducing cats who’ve gotten off on the wrong foot (or cats that will only tolerate each other), but this is just one part of a much more involved feline aggression behavior plan. The strategy was pioneered by Clinic Founder and Oxford-trained cat behaviorist, Mieshelle Nagelschneider. This breakthrough method of getting unfriendly cats to curl up next to one another again has been life changing for thousands of cats.

To Solve a Cat’s Aggression Issue You Must Learn:
- How to prevent aggression through informed selection, socialization, and training of new kittens
- Why punishment and reprimands don’t work, could make aggression worse or cause new behavior issues, and will ruin the bond between yourself and your cat.
- How to apply non-aversive and positive behavior modification methods to eliminate or manage aggressive behaviors
- That addressing the reason for the aggression is more critical than addressing the aggressive behavior itself because aggression is the by-product response of an instigating factor (either external or internal) triggering the aggression.
- Why clicker training generally is not effective for stimuli triggered aggression or types of aggression
- How to rule out possible medical causes (which can mean working with your vet) — and cure the behavioral issue even after the medical cause has been treated
- How to identify which form of aggression your cat is exhibiting: play, predatory, maternal, or petting-induced; or territorial, sexual, or pain-induced; or the little-understood but very common redirected aggression
- How to stop reinforcing or even causing/triggering aggressive behavior in your cat
- Why certain feline pheromone products are not effective (and how to use them effectively).
