My 3-month-old cat is aggressive, hissing, and growling. What to do?

Pet's info: Cat | Domestic Shorthair | Female | 4 months and 2 days old

my cat gave birth but couldnt take care of one kitten so we gave it away, we got her back and now the cat is 3 month old but she is very vicious and will hiss and growl to anyone that comes near her. She has been with us for three days and her behaviour has not changed.

Unfortunately, kittens that were bottle fed can be aggressive and not as friendly. You can try to put some feliway diffusers in the House and spray her sleeping areas. Feliway is a cat pheromone which can sometimes help to calm them. Also, give her more time. She has been moved from multiple house in her short life and now around new cats (they don’t usually remember family). This can be stressful and can take weeks for them to acclimate to. I hope this helps and she starts to get use to her new living conditions.
