kak,
thanks for the reply. No he doesn't seem to be eating or drinking. I am hoping that you are correct and that once he starts to eat again, he will be fine. He is only 2 years old and the vet is going to do bloodwork tomorrow to see if he can find out what is wrong with him this time. the last time he was sick he knew right away that he had pneumonia but this time he had no reason for him to bave a fever until he does the bloodwork. He gave him 5 days of antibiotics first to see if he improved, if not the bloodwork is set for tomorrow. i hope he is going to be ok, he is the BEST cat.
