Their tails are four to five inches long, and they weigh between one and two and one-half pounds. Black-footed ferret litters are born in May or June, usually in a litter of three or four kits. Young ferrets look like mice when they are born and their eyes are shut. When they are six to eight weeks old, the mother starts taking the kits out of their burrow. Before winter, the kits are on their own, and they leave their home territory and their mother.
