I found a cat wandering the parking lot of my apartment building and took her in, I've only had her about a month but, it turns out she's pregnant I've been feeling the kittens move for the last two weeks or so. I've never had to deal with a pregnant cat and my vet has been no help. How do I know how much longer she has to go and if she's going to give birth soon or if there's anything wrong? Please help, any and all information and help is welcome!
