How to know when my cat will give birth?

how will I know when my cat is about to give birth to baby kitten's her nipples are huge and shes really fat and stuff etc.

She may stop eating as much as usual. If your cat is really friendly then you may be lucky enough to see her contract. I would keep her in a room when you think shes really close. her nipples should look like they have milk ready you know what I mean lol.. ohh she will also start to lick her hmm hmm a lot when she is about to give birth..

she will get really lazy and even stop eating and her stomach will get bigger tan normal she will also meow a lot when you try and pick her up

Well 1st thing is to make it a place to have birth to kittens
but she should stop eatin and
She should make noises the day she has birth

she will get lazy fat and sleepy all the time

She will start looking for a place for the birth, such as your bed, closet for privacy, usually a private place.
