Aggressive Cat Behavior is Solvable: Stop feeding your cats near each other and other antiquated advice

Feline Cognition Rescue Program: scientific researched expertise for difficult cat integration and human-focused aggression cases

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?)

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.

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.  Please visit our homepage and learn more about our cat behaviorist and her work with National Geographic published works and television documentaries on the 37 species of wildcats.

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).

Frequently Asked Questions

All cat behavior solutions must take into consideration feline instincts and their evolutionary biology. The clinic has exclusive rights to Mieshelle Nagelschneider’s proprietary Cat Whisperer™ consulting, 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).

Her science-based cat behavior book, The Cat Whisperer, has been featured in the New York Times and a best-seller on Amazon and published in 4 languages (Random House Publishing with co-writer Cameron Powell).

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. We often misunderstand cat behaviors. 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.

Feline behavior therapy is very different from canine behavior therapy and the approach to changing a cat’s behavior is even more unique. Cats do not display obedience problems like dogs. The help you need is not focused on physical or verbal behavior modification strategies, like dog training with a dog trainer present. All cat behaviorists conduct consultations by phone or video via Skype. Our behavior plans are specific to cats and still allow for the natural feline instincts, but when and where you want them displayed. We will cover the behavior plan during the phone or video consultation and offer follow-up over the course of several weeks for all of our consultation programs.
