Cats have a keen sense of knowing when someone isn't a "cat person". I had the same problem with my Dad's RB cat Jessie. No matter what I did, feed her, try, as hard as I might to pet her, toss her treats, she would sit there and hiss at me, her tail all puffed out, growling. I was NOT a cat person at that time in my life. In fact, I couldn't stand cats (hard to believe, huh??) back then. I grew up with dogs. So, I just fed her, cleaned out her litterbox and left her alone. It was a long week, but we both survived. I'm SURE it had a lot to do with the fact that she was in MY apartment, not in her own environment. I didn't know any better.

You got some great advice here. Try the Bach's Rescue Remedy and Feliway and make your husband feed her and toss her treats everyday. The only thing I can add is patience. She was there first, please keep that in mind. Cats do NOT like change, and this is a BIG change in her life.

Is it POSSIBLE that he could've accidentally stepped on her paw, tail or she got under foot and he tripped over her??? Just a thought.

Please don't give up.
