I had hope that he was doing better earlier i got him to eat a piece of a vienna hot dog but oly a bite. but i just went to check on him and he looks so bad

I am waiting for the vet to call me i think i may take him in to be put to sleep i don't know what he is holding on for i have made my peace and have told him it's ok he can let go but he seems to be waiting for something and i don't know what? When i went up ther he just kept meowing and i feel thta even though the vet said he wasn't in pain that hey may be or he is very uncomfortable

I feel just awful. thanks again everyone you have been my rocks.
