Hello! I just adopted a stray and I'm not sure if she's pregnant. We've had her (Maggie) about a month, and everything I can find on cats says that when they are at least three weeks pregnant thier nipples will get bigger, and they will start to show at about five weeks! She was already showing and her nipples were enlarged when we found her, it's been about five weeks and her belly seems to be getting smaller! She doesn't like her tummy touched, she cries alot, she just recently started sleeping in the box I put out for her, she gets on our bed when in the beginning she wouldn't even go in our room! She's also started pushing really hard and having the smallest bowl movements ever!! (I watch her because a previous cat had her first kitten in the litter box and I own a litter maid!!) I can't afford to take her to the vet! What do I look for other then the obvious?
