My cat is attacking my other cat. How do I stop the aggression?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 3 years and 6 months old

Our kitty Bravo has recently started attacking one of my older cats to the point that she basically lives in the bathroom. When he sees her his body completely changes and he becomes laser focused on attacking her. We've tried the feliway infuser and a calming collar. Should be be on meds?

Sometimes this behavior can be related to boredom, frustration, anxiety or a desire to play roughly. There are a few things you can do which may help. Try enriching the environment. Here is a great article about cat's instinctual needs: https://www.petcoach.co/article/why-every-cat-needs-a-place-to-climb/ Use a Feliway diffuser, set aside 30 minutes a day for vigorous play (really get him moving) and/or switch the food to Royal Canin Calm. Provide a stand or resting place by a window so he can look outside. You may also try clicker training him for positive behavior. Here is a link about training cats: https://www.petcoach.co/article/can-i-train-my-cat/ Most cats response best to combination therapy. The veterinarian can also prescribe medications which can help with bad behaviors. I hope this helps and please feel free to post any additional questions.

    If only Brittany could talk! This type of behavior could be related to something like anxiety or to pain/discomfort. I recommend to have her examined by the veterinarian who will check for evidence of pain on the physical exam. They may also check a urine sample or the anal glands as well. Since she can't talk, it's best to play it safe. If this is related to anxiety, a few things may help at home.
