, and makes much less use of burrows. Like all the cottontail rabbits, the Desert Cottontail has a rounded tail with white fur on the underside which is visible as it runs away. It is a light grayish-brown in colour, with almost white fur on the belly. Adults are 33 to 43 cm (13 to 16.9 in) long and weigh up to 1.5 kg (3.3 lb). The ears are 8 to 10 cm (3.1 to 3.9 in) long, and the hind feet are large, about 7.5 cm (3 in) in length). There is little sexual dimorphism

The Desert Cottontail is not usually active in the middle of the day, but it can be seen in the early morning or late afternoon. It mainly eats grass, but will eat many other plants, even cacti. It rarely needs to drink, getting its water mostly from the plants it eats or from dew. Like most lagomorphs, it is coprophagic

 hunted them for meat but also used their fur and hides. The cottontail's normal anti-predator behavior is to run away in evasive zig zags; it can reach speeds of over 30 km/h (18.6 mph). Against small predators it will defend itself by kicking.

The young are born in a shallow burrow or above ground, but they are helpless when born, and do not leave the nest until they are three weeks old. Where climate and food supply permit, females can produce several litters a year. Unlike the European Rabbit, they do not form social burrow systems, but compared with some other leporids, they are relatively tolerant of other individuals in their vicinity.
