Very interesting. Elizabeth's tension matches yours? I would have thought hers to be American.
I'm sorry about your cat. We had another cat in this fuzzy family who died at age 2 1/2. She had cancer of the spleen and bone marrow (a leukemia, though she was FELV negative.) I think she got it because when we were trying to catch her when she was a feral kitten, she hid in a ceiling that had asbestos in it. The vet speculated genetics. We spent a month trying to fix her, but it was hopeless. She was the most playful and loving of the 3 kittens (to us as well as her siblings -- she would seek them out to cuddle with them). I've had many cats, but none who died so young. I miss them all so much.
