Oomi is jealous that she's been displaced.
Well, Oomi's agent needs to get me some more shots of her!
We used to have a neighbor's cat like that. She would bully her way into our house like she owned the place, until we'd finally kick her out so her owner wouldn't worry. She was elderly and set in her ways (the cat, that is) and could not be convinced that ours wasn't her house..... :)
@ Kirsten:Had your neighbor's cat ever lived in your house? Or did she just decide she liked it better, and therefore it must be hers? :)
