I had took in cat last year and found she was pregger, she had 5 healthy kittens, they all got homed. The lady that had xstrays kitten stripey gave her back to me 4 weeks ago, but i really think she is preg. They lady didnt het her fixed and said she let her out. So the least she could be is 4 weeks, i see movement n twitches, but her nips not big just little pink dots
