Okay I think I have a very sick cat on my hands. He is 16 and I rescued him about three months ago. For the past three days he will not eat and I haven't really seen him drink anything. The three months that I've had him he will not eat dry food so I feed him wet food with chicken on top. He usually goes crazy for it but he shows zero interest in it. I tried giving him milk. I know it upsets their stomachs but I needed to get something down. I have also tried tuna. He licked a little bit of the juice then loss interest. For the record I grew up with this cat and have had him since 92. I had to get him from my dad's house because my father became ill and was no longer taking care of him. This cat used to rip food out of your hands and steal it off your plate so I know something is wrong. He is extremely thin. He is an indoor cat. He is vomiting all the time. This morning there was a red tint in his vomit. He has become increasingly lethargic. And just isn't the same cat. Since this was over the weekend I couldn't take him to the vet. I have an appointment today but I just wanted to get some sort of insight before I go in and the vet starts reaming me with unnecessary charges. Help please!

Well, he is very elderly, l6 is pretty old for a cat. He could be giving up, liver problems, kidney problems, internally shutting down. Can't diangose, you understand that. This is just my insight from having some very elderly cats over the years.
