Cute 'lil critters.
The kit fox is the smallest species of the Canidae family that can be found in North America. They have large ears, between 71–95 mm (2.8–3.75 in), that help the fox lower its body temperature and give it exceptional hearing. This species exhibits sexual dimorphism, with the male being slightly larger. The average species weight is between 1.6–2.7 kg (3.5–6 lbs). The body length is 455 to 535 mm (18 to 21 in). The tail adds another 250–340 mm (9.85–13.4 in) to their length.[3]
It usually has a gray coat, with rusty tones, and a black tip to its tail.
Male and female kit foxes usually establish monogamous mating pairs during October and November. Polygamous mating relationships have been observed. Pairs can change year to year. They mate from December to February, when they use larger family dens.[clarification needed] Litters are born throughout March and April, usually containing 1 to 7 pups, and averaging 4 pups. The gestation is 49 to 55 days.
Pups do not leave the den until they are 4 weeks old. They are weaned after about 8 weeks and become independent at 5 to 6 months old. They become sexually mature at 10 months. Both parents take part in raising and protecting their young.
The average lifespan of a wild kit fox is 5.5 years. In captivity, they can live 12 years. One California study of 144 kit fox pups showed a 74% mortality rate in pups within the first year.
