My kitten that is about 10 weeks old is has been acting strange today. He has been distant and lethargic. He has not eaten much, and he has acted like he wanted to throw up several times, but can't get anything up. He is not playing at all, and is just generally not acting like himself. I am really worried, but we have no emergency vet here. He has been in the litter box several times, and I can't tell if he's trying to have a bowel movement and can't or what. He is acting depressed. He will just look at me with these sad eyes. I don't know what to do. I will definitely take him to the vet Monday, but what do y'all think?
