Her kidneys are okay, although she’s dehydrated. She has a liver condition caused by not eating. I forget the name of the disorder, but kitties with whatever this is become anorexic. The more they refuse to eat the worse it gets.
The only other option is hospitalization and a feeding tube. I’m not doing that to her.
Oh, too bad. And I agree, “heroic measures” for a pet in very old age are just cruel.
