How far along is my cat?

I have about an 11 month old cat who seems to be pregnant. I have been able to see and feel movement for about a week now. Her nipples seemed to have grown very large and are a bright pink color with a white crust around them and have black specs around the bottom. I wasn't sure what that meant and I was wondering with these signs about how far along my cat is. The kittens have been moving around very quickly lately and it's very visible when you look at her.She's been sleeping about all day every day. Can anyone tell me how far along she is?

Kittens moving isn't usually obvious until the last two weeks.

Remember she can get pregnant again while feeding her kittens so she needs keeping in until they are weaned and then spaying.  She also needs to be given as much good-quality cat food to eat as she wants from now until the kittens are weaned.

Alright thanks for the help! Is there any really obvious signs that I will see before she is about to have the kittens?

Poor girl being pregnant so young. Do you know when she was outside or around an entire boy? You can just count 65 days from then for an approximate due date. 

Some girls nest, digging around in the kitten pen (that you've hopefully set up for her). Some go off their food, others eat up to the point of delivery just about.
