Thanks everyone. Before I went to bed last night, Sunny did eat some of his food. I was hoping that I wouldn't find any more throw up this morning and I didn't. While I was getting the food prepared, Sunny started meowing and acting very hungry like his old self. He ate all of his breakfast this morning so I think that whatever it was has passed. I'm going to cancel his appointment but I want to wait a bit to make sure that he doesn't throw up again. Pearl is still very concerned about Sunny and she keeps on trying to get close to him and sniff and lick him. He just seems anoyed sp? by all of this attention. His energy level is still not what it should be but I feel that by tonight he'll be much more back to normal. Thanks again.
