Oh, I have such sympathy for you!
I had a room mate once who really hated my cat Scooter, for no good reason.
She had a cat, RJ who was poorly trained, and was always jumping on the counters, killing plants and picking fights with my other cat Clyde. And whenever anything was broken Scooter got the blame insted of RJ.
She is a big part of the reason that I now live with my sister! My sister LOVES Scooter, and has 4 cats and a dog of her own, so I knew that Scooter, Clyde and I would fit in well.
