I have 2 female cats that I have raised since the day they were born , recently one of them has had a litter of kittens. The sister has become very angry towards the new mother growling and hissing , the mother is still loving. The sister just looks mad at the mother but still is nice to everyone else , even the dogs. Signs of anger were detected about 2 days before the mother gave birth when she slightly growled while being held by some company we had over , which was extremly odd , but now its day 2 of kittens and I'm wondering if this is normal and if they will go back to normal?
It cut my last question off for some reason , heres try number 2
