Cat

Question
i have Siamese cat, she is pregnant , and she eat very little food,
please tell me which food and medicine i give her,

Answer
She should be feeding kitten food free choice. Not adult food but food for growing kittens.

She only needs that- a good quality food like Science Diet Kitten Growth. Get that or something equivalent. No medicine unless she is ill and then only a vet should give her that.

Just pour her a bowl and let her eat all she wants until the kittens are weaned. If she continues to NOT eat then she needs to see a vet right away.

Hopefully she is vaccinated for the most common cat viruses.

Get her into the vets if she isn't eating well. If she is eating a high quality food now then maybe she is getting all she needs. Most cats will eat until they meet their energy needs met.

If she is not doing that then get her in to see a vet as soon as you can.
