Oh boy. I think my oldest kitty is giving up. Won’t eat or drink unless I really coax her and give her food with more protein than she should have. Not cleaning herself much either. Already on thyroxin. Well 20+ years is a good run. Luckiest cat alive, on her 3rd human family. First one gave her up in a meth haze, second owner died in a hiking accident. My lap cat is fading away. Her frame reminds me of the old horror flick “Thinner”. Vet does the best he can but time/entropy always wins.
