Hello. My kitty is 8 months old. My friendly pitt is 11 years old. He ignores her completely. She does not like him. I had her since 11 weeks. I friend gave her to me. She was well taken care for. Not abused. She used to scared of the dog but now seems to hate him and tries to attack him. He just walks away. I'm very scared he can bite her one day in defense. She was a sweet kitty before spaying her at 5 months. she is attacking me randomly too for no reason. Nothing has changed in the house. I'm also scared for my 6y old even though she is ok with him mostly runs away from him when he wants to play. He is gentle. I dont know whats going on. She bites and scratches. We dont play with hands. She has toys and scratching posts and tree. Please let me know what you think. This is my first cat. She draws blood on me and I'm immunocompromised. Could it be an adolescent stage? Please help!
