She wasnt like that at all, she is very loving to us and her kittens, but today i realized she was acting weird, she scratched me, i cant even touch her now, and she wont let her kittens come near her, verytime they come a little near her she will start hissing and she will bite and scrath them, they are almost 5 months old, what's the matter with her? What should i do? I have scratches all over my hands, she never scratched before and she used to love it when i petted her but everytime i tried to pet her today she would scratch me, i need quick replies
