I had a cat (RB now but I still miss her a lot) who did that to whoever entered our house. She was very sweet and never attacked us but strangers, even relatives who were not mmy sisters, my parents and myself were a bit NO NO. The only other person she literally fell in love with was my sister's ex boyfrieds. With him she was as sweet as pie. I never understood why.

Sorry I can't be of more help. Welcome to Pet Talk!
