My male kitten who is getting neutered in 2 days is about 4 months old and he's constantly chasing and pouncing on my female cat (not in a sexual way, he appears to just be playing and being ornery). He's a total sweetheart but he's driving her insane and she always growls and hisses at him to make him stop but he doesn't...Do you think neutering will help him calm down or is he just doing this because he's a baby still? I had a female kitten before him that I rescued and she didn't do this..
