How can I tell how far along my cat is?

Question
I'm pretty sure she might be pregnant, She's a little over a year and we have a young male cat, who is nearly a year himself. She hasn't been in heat.. for maybe.. 46 days.. aprox.. so would that make her 46 days into her pregnancy? She has a small belly, but she is a tiny cat. Her nipples are also very noticeable and are very pink. She's been wanting a lot of attention, but that's how she always is with me. I can probably get a picture of her onto my computer..

Answer
Hi Jeni, well if it has been 46 days since she was in heat then indeed that is a good guideline to go by. She is most likely pregnant because she has the pink nipples and is attention seeking and she would be  46 days pregnant give or take a day. She will start to show in the next week and you should be able to feel the kittens moving next week also. Teresa
