Pregnant cat hissing at new kittens: How to ensure a safe birth?

She is likely to become more protective when the new born kittens arrive and it is unlikely she will become more accepting of the older kittens at this stage. Ensure she has a quiet area to have the new kittens undisturbed y other cats (including her previous offspring)

I would recommend waiting until your female cat has had the kittens before really changing anything. IT is possible she is protective and unfriendly to the other cat due to being pregnant. You can get feliway a cat pheromone to help decrease stress in the house. Also, you can try to increase litter boxes and areas of elevation to help calm the two cats. I hope that helps

I would move your heavily pregnant cat to her own room away from the kittens so she can focus exclusively on her kittens. I'd place her in her own room with her own food, water, litter box, and whelping box.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I wouldn't allow the other cats in the room during labor. Despite them all getting along under normal circumstances doesn't mean their presence during labor won't stress Lovely. When cats are stressed during labor they can delay delivery of the kittens. She should be in a quiet room that is familiar to her. The number of people should be limited. With one person checking on her every few hours. As for after the kittens are born I wouldn't allow the other cats in the room without you. Again just because they get along doesn't mean that one of the cats won't hurt the kittens. It's best to be safe than sorry. I hope this helps and I wish you all the best!

This is the time of year when cats start to come into heat again, and if she isn't spayed and there is an intact male nearby, she may be going into heat and trying to push away her previous litter in order to make room for a new one. If you do not wish to have more kittens, I highly recommend having Chloe (and the kittens) spayed if the male cannot be. 5 cats (plus the others you mentioned) is also a lot of cats, and the sheer number may be very stressful for her. Finding homes for the kittens, or making sure everyone has access to their own food, water, bedding, litter, etc can help decrease tension.

It is recommended that when a cat gives birth that she is in a quiet room of her own. It helps reduce stress, and female cats can get protective when their kittens are born. It's best to place Jess in her own room when she is close to giving birth and keeping the dog out of the room.

Yes, it is normal of a mother cat to be protective of her unborn kittens. I would keep her previous litter away from her until after her new litter is at least six weeks of age when they start weaning.
