the vet did look all in his mouth and she said that it didnt look like there was any sores or any teeth that could be absessed however no blood work was done because at the time I did not have the money to get it done and of course she wouldnt let me set up a payment plan even though it has been my vet for 11 years. She gave him a shot of an antibiotic there and gave me (Vedco) Clinda Cure antibiotic to give him twice a day for 10 days to see if anything clears up. My cat does not have or ever had loss of appetite and he drinks lots of water but he drools alot and he is very much skinnier. He even meows (talks like he always did) and still wants to go outside but I dont let him out. He has been like this for almost 3 weeks now and a week on antibiotic. Oh and his left eye is squinty so that is what i thought from the beginning that it was a tooth or a sore on that side makin his eye squinty and have discharge. I dont know if I should just get him put to sleep or if he can have a chance and get healthy again. He doesnt seem like he is in any pain which is good and the vet didnt think he was in pain either but the tongue sticking out, drooling, and getting skinny are a very big concern.
