Aggression in cats (or ANY animal for that matter) can have many causes but if you’re dealing with an angry cat, here are some tips:
1. A veterinarian visit is crucial if your cat is beginning to show even the slightest hint of aggression or change in behavior. There may be an underlying medical cause for the behavior. The sooner you detect the behavioral change and have it checked by the veterinarian, the greater the chance of avoiding an escalation of the aggression. It could be anything from a painful abscess due to a cat fight, arthritis or hyperthyroidism, to name just a few. Don’t skip the vet exam. If your cat gets a clean bill of health then it’s time to use your “think like a cat” detective skills.
2. If you know your cat isn’t feeling well or you can tell by his body language he’s getting agitated, prefers not to interact or is getting stressed, provide a safe place for him. Be proactive and offer him a place to safely chill rather than test his tolerance.
