My adult cat is biting my new kitten. Is she trying to kill her?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed

I have an adult female cat and a 9 weeks female kitten, the adult cat walks behind the kitten and she tried to bite her on several occasions.. would she kill her? Btw she is not hissing or growling.. but she always look like she’s ready to attack!

Unfortunately it is impossible for us to know if this is a type of play behavior or if this is related to prey drive since we cannot observe the behavior. Certainly an adult cat can seriously wound or even kill a nine week old kitten. I recommend to keep them separated until you are sure they get along and the kitten is bigger. You may do some research about cat behavior. You will need to look at the position of the head, mouth, ears, spine and how the fur is laying. That will give you a better idea of your adult cats intentions. You should also make sure to spend at least 30 minutes a day exercising the adult cat. This will help to make it more tired and less likely to exhibit bad behavior. Best of luck.
