I've been thinking about asking my vet about prozac for our Bengal Rocky that is aggressive to all our other cats, but she only attacks my other older girl cat Grey. She'll upstairs and pick fights with her. Grey wont even come downstairs anymore because of it. My house is pretty big so it's not like she's confined to a small space, but nothing is really working to get Rocky to stop being aggressive and it's been an ongoing problem for more than 2 years.The reason we put Monte on Prozac is because he had a few incidents with redirected aggression where he attacked our other cat and myself.
