So about a month ago my cat stopped eating normally. He usually eats all of the food in his bowl but he had started only eating half. I didn't think much of it because we had this problem before and it turned out he was just getting to many treats. So after about a week or two nothing had changed, and things were getting worse. He has started eating less each week and this week he's eating less than a spoonful a day and today he didn't eat or drink at all. He has also stopped letting me pet him. I don't think he is going through a phase or anything because I have had him for 5 years (he is around 9 or 10 now) and he never does this. It kind of seems like he wants to be pet by me, but for some reason he can't. I have an appointment with the vet in two days but I'm afraid that he is starving and I don't know what to do, please help me!
