When referring to reproduction, the word “gestation” is used to describe the carrying of unborn offspring inside the uterus of a female. To be a bit more specific, “gestation” is used to describe carrying the unborn offspring of viviparous animals, which are animals that give birth to live young (as opposed to animals that give birth through egg-laying, for example). Gestation begins at conception and ends at birth.
It is possible, and not uncommon, for a female to experience multiple gestations at the same time: A cat for example, is like to be carrying several kittens in her uterus instead of just one.
Pregnant Cats and Kitten Fathers
If your cat is expecting kittens due to a planned pregnancy you probably know who the father of the kittens is. However, did you know that a female cat can mate with several different males? This means that if your cat is expecting kittens due to an unplanned or unsupervised mating she could could be pregnant be several different fathers. This is a common situation when an un-spayed female house cat escapes the house, or when you adopt a pregnant stray.
