My cat had 4 kittens on Friday (3 days ago) she is doing well as are the kittens but she still looks like she has 1 kitten inside. What I want to know is, is this possible? I know cats can get pregnant by 2 cats at the same time so does that mean she would give birth at different times to? My mom said she thinks she can remember my sisters cat having kittens then a few days later having another 1 but I can't remember. And also if this is the case would the kitten be ok? I don't really want to phone a vet as it sounds silly saying it out loud.
