Please Help.

It could be a number of things.Your kitten is very young and as far as i am aware their stomachs are very tender at a young age causing them to be sensitive to food.Have you ruled out worms ? as they can take nutrients out of the kittens body.If your kitten has swallowed something then it could cause a blockage (oviously an exray would show that up)Why don't you key your question in... on the internet and see if other people have had a simular situation to you.Try not to worry too much you will soon get to the bottom of what's wrong,good luck :)

Hospital ? I hope you meant you brought your kitten to the vet, not the hospital for humans ? Vets are very competent people in general and they know their business.

Know one thing : avoid milk. It's not suitable for a cat (and even for us !). The only milk suitable for cats is that of their mother. Do not give milk to cats in general.

Besides, there are specific food for kittens vs. adult cats. Young animals have very specific needs, like young children, in terms of growth, for example.

Last, like for young kids, be careful with the toys the kitty may have. They may swallow them easily and this may have caused internal problems. Young animals are very playful and anything can become a toy - and a dangerous toy sometimes. They are to be watched over like boiling milk !

Was there blood in what he threw up ?

Anyway, you noticed many things really helpful for the vet to know. It's very important to notice this kind of details and be attentive to changes in behavior as this is the way to see there's something wrong in an animal.

Hope your little fellow will get better. Let us know !

my way is to have a vet to check on him/her. vets are skilled people that know how to help animals. (thats what i know)but still a vet would be good. i would do the same and i hope your cat gets better mkay?

Sorry,i don't know what to do.B'cause it all fate.

well i have had to take care of a lot of kittens that needed help and were still young. can he get up and move around?

does everybody forget vet?
what could you do exept bring it to the vet??

Sounds like roundworm if it gets to bad cat can die...

I don't think he could die. He's just sick I think.
My 1 1/2 year old cat Leo pees in random places. We thought it was spraying, but he's neutered. He had medicine and stuff, but he's OK.
I suggest you try different foods. My cats will only eat dry food, I thnik they're scared of wet food or something.
And I red your comment on the 1st person's reply about how the last time your kitten pooped it contained string.
My other cat, Teddy, eats string he finds in my room. Then, he pukes it up a day or two later. He's never pooped it our before. Is there string lying around your house? If so, you might wanna clean it up.
You should do X-Rays. It's a pretty helpful way to fin out what's wrong. Maybe he ate something inedible and it's stuck in his stomach so he's too much pain to eat? IDK.

Cute cat by the way.

yes put him down. if he is in pain for sick put him down because if u where a cat and u where in pain u would want it to go away. So take him out of his misery. Sorry

Feed it its fave treat or send it to a emergency medical vet.(Specialist)It could have a 'rare desease'
