My cat rook (hes around 15 years old, and a tabby i believe) stopped eating after we moved, so we took him to the vet and got some bloodwork and they said he had an infection but we couldnt tell what kind of infection it was and they gave him some antibiotic. It didn't work, he still isn't eating, we try to feed him wet food but hes starving himself, he's barely got any muscle left and he cant even jump on my bed by himself anymore. Since he hasn't been eating solid food (or barely any food) his poop is liquidy, and it seems to be bothering him, i tried to clean him with wet wipes but he seemed too bothered so i stopped... im just lost because ive never had to deal with anything like this
