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 你 ruled out worms ? as they can take nutrients out of the 小猫 body.If your kitten has swallowed something then it could cause a blockage (oviously an exray would 显示 that up)Why don't 你 key your 问题 in... on the internet and see if other people have had a simular situation to you.Try not to worry too much 你 will soon get to the bottom of what's wrong,good luck :)

Hospital ? I hope 你 meant 你 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 牛奶 suitable for 猫 is that of their mother. Do not give 牛奶 to 猫 in general.

Besides, there are specific 食物 for 小猫 vs. adult cats. Young 动物 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 吞, 燕子 them easily and this may have caused internal problems. Young 动物 are very playful and anything can become a toy - and a dangerous toy sometimes. They are to be watched over like boiling 牛奶 !

Was there blood in what he threw up ?

Anyway, 你 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 小猫 that needed help and were still young. can he get up and 移动 around?

does everybody forget vet?
what could 你 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 年 old cat Leo pees in 随意 places. We thought it was spraying, but he's neutered. He had medicine and stuff, but he's OK.
I suggest 你 try different foods. My 猫 will only eat dry food, I thnik they're scared of wet 食物 或者 something.
And I red your 评论 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 日 或者 two later. He's never pooped it our before. Is there string lying around your house? If so, 你 might wanna clean it up.
你 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 由 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 或者 send it to a emergency medical vet.(Specialist)It could have a 'rare desease'
