Foxes typically sleep in dens, especially when they have their young. There are exceptions of course, as some males will sleep in the open when it is mating season.
Often, foxes will also use a blanket of snow to keep them warm when a den is not nearby. Foxes are found all throughout the world and live mainly in wooded areas where resources are plentiful. Foxes live alone except for a few months out of the year when mating season comes around, mainly in March and April. Most species of foxes are rather small, weighing in at less than 15 pounds. Though their stature is not great, they are very clever and quick.
The female fox gives birth in the springtime after mating. The young, also called kits, are born in the den built by the adult fox. Foxes can have up to 10 kits each season, and the mother typically returns to the same den each year when it is time to give birth. The mother feeds the kits with regurgitated food until they are ready to start eating small animals and insects. Within a couple months of birth, they are ready to hunt on their own. Foxes eat a variety of prey and vegetation. They are not picky and will even feed on insects, berries and rodents.
