For the first month or so of their lives, red fox kits remain in their den. They are born with a coat of dark gray fur, which is replaced when they are about a month old and starting to emerge from their den. Their second coat is sandy-colored and blends in well with the soil surrounding the den entrance, where the kits spend most of their time. By late June they will have acquired the red coat we associate with adult red foxes. Meanwhile, if you know the whereabouts of an active den, there is no better or more fun time of year to watch the antics of young kits than right now – they entertain themselves while their parents are out hunting by pouncing on each other, having mock fights, playing tag and chewing on all kinds of things from sticks to feathers – all of which is interspersed with frequent naps.
