Anytime a kitten/cat starts to "sleep all day, barely plays, barely eats", or does not act his/her usual self, it's a big warning signal to see a vet right away.
Have your kitties been to a vet recently and have you explained to them about his eating/vomiting habits when you went in for his vaccinations? There could be other unrelated issues, but a vet check is really what I would've done first.
Another thing about feeding...I couldn't tell from your post, but I used to feed my kittens about 1-2 oz during each feeding, but fed them up to 4-5x a day! Kittens eat small but frequent meals. Maybe you were feeding him too much, and he gobbled up too quickly? That can cause some vomiting issues sometimes. Bile usually means he went too long without food, so again, it may have to do with how frequently he's fed or not.
To be honest, I didn't start my two on raw at 3 months of age. Young kittens have an under-developed immune system, so for their sake and to be on the safe side, I didn't give them raw meals until they were at least 6 months old. I also fed my cats a lot of canned food before transitioning to raw and completely eliminated kibble when I did. There's this whole controversy about feeding cats dry and raw at the same time, so I just stuck with canned/raw. I think it's good to have some cannned food on hand, because kittens and cats can have "off days" in my experience, and feeding them their favorite good quality canned food temporarily is certainly better than not having anything else for them to eat. That way, they'll also develop less negative associations with raw food if they continue to feel sick, too.
Hope others can help add to your thread. I just want your kitty to get better! Sending well wishes to you both.
