2 months ago my sister-in-law moved in with me and my husband. My cat(11 months old female) didn't really notice her, she would go up to my sister-in-law and sit in her lap from time to time but otherwise didn't really mind or notice her.A little over a month ago my cat had to go stay at my moms house twice while we where having some work done in our old home and she could not be around and she was very unhappy after that not letting anyone touch her or come near her for a day or so. Then A month ago we moved to a larger place and ever since then my cat has got more and more aggressive towards my sister-in-law. She has gone from every once in a great while hiding behind something and jump out at her to now chasing her around the house with the hope of pouncing on her foot or scratching her leg. Each time this happens my sister-in-law claps her hands together or snaps and says no. My cat has also gotten to the point where she will not let my sister-in-law walk through the house without watching out for her most of the time.
I think this may have to do with her associating all the changed in her environment to my sister-in-law living with us and that is why she is acting out towards her. But this is just a theory. Is there anyway that I can help her stop pouncing and stalking my sister-in-law? We have tried startling her away from these actions when she doing/does them and not showing her any affection for a while after she does these things, is there anything else we can try?
