The Red Fox mates from January through March. The female will make one or more dens right after mating. The extra dens are used if the original den is disturbed. A little less than two months after mating, the female gives birth to a litter of between one and ten kits. The male brings the female food while she is caring for the kits. The kits start playing outside the den when they are about a month old. The mother begins feeding her kits regurgitated food, but eventually she will bring them live prey to “play” with and eat. Playing with live prey helps the young kits develop the skills they will need for hunting. The kits leave their mother when they are about seven months old.
