What does miscarriage mean for a cat?

A miscarriage is when a fetus is delivered prior to the point of viability. In a cat, a miscarriage can happen at any time during gestation. The good news is, miscarriage of one fetus typically doesn't affect the rest of the litter. However, you should keep a very close eye on your cat if she does miscarry one kitten to make sure she is doing fine with the rest of the kittens.
