My Girl Is An Inside Cat, Unfortunately the door gor left open and she snuck out about 5/6 weeks ago,her nipples look pink but shes white so im unsure if thats regular
If they are pinkier than were, its probably so. They use to pinkish up quite exactly on day 21...
But yeah, quite so few of these - "the door happened to be open, and she happened to sneak out" - the do become preg.
Because its no pure coincidence. This happens quite more often when they are in heat, and they feel a tom nearby, than when they arent in heat....
ps. And a tom happens to be nearby, because the tom isnt stupid him either, he too feels the smells of a female cat in heat... so he is nearby.
