How far along is my pregnant cat?

Question
I noticed my cat starting gaining a belly 3-4 weeks ago. This is her second pregnancy. She had 8 kittens her first pregnancy. She is not as large as she was in her first pregnancy. And I can feel the kittens moving. So is there anyway I can tell how far along she is with that info?  

Answer
Hi Brianna, When you start to feel the kittens moving is usually when the cat is 6-7 weeks gestation. A cats gestation is 9 weeks in total so she will be due soon. Are you going to get her spayed ? You will want to be ready to do that when the kittens are 6-8 weeks old before she gets pregnant again.
