Hi, I'm almost certain that my pregnant cat has been in labour for over 31 hours, yesterday morning she passed a little bit of blood, but nothing since then. Right now she is laying on the floor breathing very heavily, and her eyes seem to be rolling into the back of her head, earlier tonight she was meowing quite a lot, as well as being extremely affectionate. She has also not at all been interested in her food, which isn't normal for her. Her kittens have also been a lot more active the past few hours. I'm just wondering if all of this is normal? Should I be expecting kittens anytime soon?
