Aggressive Cat Behavior

Aggressive cat behavior is among the most challenging to owners. “I have a very very very angry cat,” some clients tell me. “I have a mean cat,” say others, or “a mad cat.” 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 figure out what kind of aggression your cat is displaying. Many types of feline aggression are normal, but all can be modified, with the right expertise. If your cat is attacking you or other humans, or you want to learn how to prevent misplaced aggression, read on. (Is your cat fighting other cats?)

The Cat Behavior Clinic is also the home of The Nagelschneider Method, a way of reintroducing cats who’ve gotten off the wrong foot. Pioneered by Clinic Founder and Senior Behaviorist Mieshelle Nagelschneider, this breakthrough method of getting unfriendly cats to curl up next to one another again is exclusive to The Clinic — you won’t find it anywhere else because she holds the latest research in animal behavior from Harvard University. Read our clients’ success stories and see why the Clinic is your best chance of stopping all behavior problems now.

In your behavior consultation with one of our expert behaviorists you’ll learn:

  • 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 owner
  • how to apply non-aversive and positive behavior modification methods to eliminate or manage aggressive behaviors
  • 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 unwittingly rewarding or even causing aggressive behavior
  • how to prevent aggression through informed selection, socialization, and training of new kittens

And much more. Read just some of our testimonials on solving feline aggression issues. Aggression is one of the most challenging behavior issues. You need experienced, professional help. Book a consultation today.
