pregnant cat

my 11 month old cat is pregnat and not sure when she breed i can feel the kittens moving inside her and was hoping you could give me an idea of when shr may give birth,

If you had gotten her spayed before she got pregnant you wouldn't be wondering.
   
Take her to a vet.
   
Before you go make a list of questions of things you should have known before you decided to breed her, like what to feed her during pregnancy and nursing, what to do if a kitten gets stuck, and how many kittens are euthanized in shelters due to overpopulation (thanks for adding to it!)

   
For one thing I didn't breed her on purpose , she got out when my little niece opened the door, i was and am planing to spay her. but thanks for the info anyway
