My male cat is aggressive. Will he hurt pregnant female or kittens?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | unspayed | 6 months and 5 days old | 7 lbs

We have 2 cats that are about 8 months old. We recently noticed that our female cat is pregnant. By the signs she is showing she could go into labor within the next 2 weeks. This is her first time to give and the father is constantly trying to mount her. We live in a single bedroom and dont have a private bathroom to separate them. He's not hurting her now but has always been dominate and can play a little aggressive. Will he harm her or the kittens?

Yes, he can harm the kittens. Some tomcats have attacked and killed their own offspring in order to get the attention of the mother cat, and bring her back into heat so they can mate again. Since you have a single bedroom, I would keep Ash in the bedroom alone and do not allow the male cat in with her or the kittens. Best sure to keep a litter box, food, and water in there for her. If that truly won't work, I recommend having him staying somewhere else during the first couple of weeks of the kittens's life to prevent him from hurting them. I hope this helps.
