How big does a Swift fox get? Here is an overview over the average adult age:
A grown Swift fox (Vulpes velox) reaches an average size of 50.5 cm (1′ 8″).
When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 20 years, they grow from 40 grams (0.09 lbs) to 2.11 kg (4.66 lbs). A Swift fox has 4 babies at once. The Swift fox (genus: Vulpes) is a member of the family Canidae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
The swift fox (Vulpes velox) is a small light orange-tan fox around the size of a domestic cat found in the western grasslands of North America, such as Montana, Colorado, New Mexico, Kansas, Oklahoma and Texas. It also lives in southern Manitoba, Saskatchewan and Alberta in Canada, where it was previously extirpated. It is closely related to the kit fox and the two species are sometimes known as subspecies of Vulpes velox because hybrids of the two species occur naturally where their ranges overlap.The swift fox lives primarily in short-grass prairies and deserts. It became nearly extinct in the 1930s as a result of predator control programs, but was successfully reintroduced later. Currently, the conservation status of the species is considered by the IUCN as Least Concern owing to stable populations elsewhere.Like most canids, the swift fox is an omnivore, and its diet includes grasses and fruits as well as small mammals, carrion, and insects. In the wild, its lifespan is three to six years, and it breeds once annually, from late December to March, depending on the geographic region. Pups are born anywhere from March to mid-May, and are weaned at six to seven weeks old.The swift fox is closely related genetically to the kit fox (Vulpes macrotis), but occupies a different geographical range. The two have historically been regarded as different species for reasons basically related to size: the kit fox is slightly smaller than the swift fox, and the former has a narrower snout. However, hybrids between the two occur naturally where their ranges overlap, and some mammalogists classify the two as subspecies of a single species, usually treated as Vulpes velox (with the swift fox being described as V. velox velox and the kit fox as V. velox macrotis). The molecular genetics evidence is not conclusive, however, and some of those who have used it continue to treat the swift fox and kit fox as separate species.
