Re: New kitten hurting older cat?
My female was 4 when I adopted a 5 month old male (last year), and from my experience the male is just trying to dominate the female, thats what males do. My male is still slightly aggressive towards my female, but when hes not chasing after her they get along great. If your kitten is anything like mine, one thing I would watch for is if he starts bothering her when shes in the litter box, because my kitten still sometimes does that, he will just go over and start sniffing around when shes trying to do her business. One thing that could help and make your kitten realize he shouldnt be attacking the female is everything he goes too far and maybe bites her or something, seperate him into a seperate bedroom for a few minutes to let him calm down. Good Luck!
