How's today going? If I may ask, are you working, or home with the cat? What's the health issue?
Just got back from dropping Bindi off at University of Tennessee. I don't know how much more time we have; I can't imagine that it would be a year. She's only 9. I began retirement last year, and thought I'd have years of her health. Trouble began almost immediately; really I think there were some signs a month before. I don't think she has any idea there's something wrong. And I really can't treat her with food, as that's central to the problem. I almost killed myself last year taking care of her. I've committed to going easier on myself this year, and somehow, mercifully, it seems to be working.
It may be the wrong time or too early to say, but you can have more of that joy and love, again, with an adoption in the future. I don't know if I could ever live without a cat. It would be good for both of you. Meanwhile, take care and good luck. Let us know what's going on.
