I've had two cats at the same time, who never got along for thirteen years. They both lived long lives, 18 and 19 years. Now I have adopted a cat that I knew had feline leukemia from birth. They told me she had a life expectancy of two years, but she looks great and will be 5 years old in March. I didn't want to get another cat because of her disease. I didn't want the heartbreak of losing two young cats and can't afford the vet bills right now. But now for months she sits and stares a long time at herself in the mirror every night. Then she scratches at the mirror and tries to figure out a way inside it. She keeps going nose to nose with herself in the mirror. I've never had a cat do this and since it is every night, I think she may be lonely for another cat. Has anyone else seen this behavior? Thanks.
