Hi I have 2 female cats mom and daughter, both have been fine together until recently. The mom (simone) got out the other night, and we could not find her. She made her way into the garage I had left open for her in case she would return, I found her wounded. She is getting better everyday, but now sascha is mean to her, sniffing hard and growling, even attacking her. What is the deal? Please help me!
