Dens are used during the year for daytime resting, escaping predators, avoiding extreme heat, preserving moisture, and carrying and rearing young. Kit Foxes will dig their own dens, but they can also modify and use the burrows of badgers, ground squirrels, prairie dogs, and kangaroo rats. Dens are spread across the home range, and an individual fox usually uses more than 11 dens in a given year. They normally rest in their dens during the day, but sometimes can emerge to bask and, when pups are young, to play.
