When I was younger we used to be the house that everyone who had a pregnant cat. Would come and drop them off at our house. We didn't want them people just dropped there cats off. A lot of the time when the kittens we're about 4 to 5 weeks old they mom would up and leave and wouldn't come back. So we had to take care of them. So this set of kittens is no different, its just been a LONG while since we have had a pregnant cat or any cat for that matter. We had to put our cat of 15 years down last August. So having kittens running around is soothing =).
