Kittens coming!!

So I am sure this has been answer a hundred times!! My cat is small and having her first litter... 16 days ago we went to the vet to get spayed and she was already pregnant and they told us she was at least 2/3 if not more along! I have been able to see them move for over 2 weeks and her nipples are very large! She still wants food but is licking herself more than normal but not a ton! Any chance of knowing when they maybe could come??

she is my first cat and I'm not sure of anything...

Welcome! Sounds like she is getting very close. Maybe another week or so since the vet said two-thirds not quite two weeks ago. The grooming becomes more excessive as their time draws near. Do you have a nest set up for her?
