Why is my cat still aggressive after neutering? Feliway isn't helping.

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

I got my cat Batman fixed 12 days ago because of his destructive behavior and aggressiveness towards one of my female cats. I have three cats, two females and Batman's my only male cat. He is only aggressive to one of them, I bought feliway multi-cat diffuser the day I got him fixed and he is still misbehaving. What can I do?

It takes 4-6weeks after neutering before the hormones and related behavior subsides. Be aware however that not all bad behavior is hormonal and some cats will never be friends and many need to be segregated. Calming diets and supplements such as kalm aid can help alongside the feliway
