my cat is 13 years old. he's had a history of urinary tract infection. i've taken him to the vet, the vet gave vitamins, IV, and antibiotics. cat is acting very strange, he keeps hiding in dark areas, wont eat or drink, eyes are dilated, will not move from the corner. not sure whats wrong with him, anybody experience this before? i've been doing a lot of research and from what i see is it possible he is preparing himself for death? i can't possibly lose this cat is there anything i can do to help him. any input will help, thanks!
