My cat had one kitten tonight about an hour ago and hasn't had any since then. This is her second litter and the first litter she had 4 kittens and one still born. I am just wondering if it's possible if my cat could only be having this one kitten. She is not contracting and is acting perfectly normal; eating, drinking, playing with my dog. So I don't think she is having a complicated pregnency. If she isn't only havig one baby, what's the normal time frame in between each kitten born?
