WOW I've never read something like this!

My thought was to rub some catnip on your hands, and take some catnip to her as an offering. See how she reacts. It would help to know he has given her catnip in the past, and that she is like most cats, rolls in it, has a blast and then sleeps. It gives them a positive feeling. I'm thinking this would help give her a positive feeling towards you.
