My cat don't eat and vomits

Take it back, it is defective.

Please take you cat to the vet as soon as possible.

You need to take your cat to the vet ASAP. The vet is the only one, who is going to be able to find out exactly, what is causing your cat to not eat and vomit and be able to treat the problem correctly and effectively!

Hiwiseguy, if you cannot respond with care and compassion, then please do not respond at all. This was the first post of a new member, and yours was the first post he/she saw, notice how the OP hasn't been back since? You're post was unkind and uncaring, and not at all helpful, but hurtful. You won't last long on this site if you cannot show some compassion and understanding.

Good luck.

It sounds as if your cat has a bowel obstruction of some sort, which can be fatal if not treated by a vet!

A vet is definitely the only way to go in this situation. If it's something that can be corrected then the sooner the cat is brought to the vet the better.

Good luck.
