I got my 1.5 year old male cat neutered exactly 2 weeks ago. His incision healed nicely but the his behaviour did not change. The only thing that i noticed is he isnt restless that much anymore. He still fights with neighbours and stray cats that come into my garden. I feed 2 stray kittens that are 8 months old and they hang out in my garden with my cat. Even after neutering he still wants dominance over them, bites their neck and pins them down. I've read that it can take up to a month for hormones to go away from his body but im afraid his aggression wont change. Did someone have a similar experience? Im really concerned.
