Cat reproduction

Keeping on the animal weird sex theme established in the last posting, we have a weird one from a species both near and beloved: the house cat. It's one dirty bitch. Once a female cat and a males cat ehhem... do it, and the female gets prego, the female cat can keep looking for new males and get double pregnant by a different dude. With most non-cat species, once an egg gets fertilized the whole system goes into to baby mode and stops producing fertilize-able eggs. However there's no particular reason to shut down normal reproductive stuff at conception especially if a species has multiple babies per litter and the first round of babies/kittens is only a few days post consception. After ehhem... conception round 1 female cats go out and actually try super hard to get pregnant again and so kittens of the same litter can be half sibs.
