Very few pups remain near the area they are born, and dispersing pups have been captured up to 32 kilometers from where they were tagged. Dens belong to specific individuals or family groups, and den ownership may change from year to year. Dens usually have 2 entrances, but they may have up to 24. Tunnels can be from 3 to 6 meters long and to depths below 1 meter. Den changes may be related to the depletion of prey in nearby hunting areas or to the buildup of ectoparasites within the den.
Kit foxes make several different vocalizations.
Kit foxes also make soft growling sounds and high pitched, repeated barks. Habitat Kit foxes are associated with desert and steppe climates. The decline of this subspecies is due to illegal hunting, and poisoning or trapping related to coyote and rodent control. Coyote control may lead to kit fox mortality through accidental trapping and poisoning, and rodent control may increase mortality through prey reduction and secondary poisoning. Because kit foxes often den many miles from water, they must acquire adequate moisture from their prey.
