in a distinct tuft. The head is relatively large, with prominent rounded, hairy, ears. The hind legs are unusually long for a rat, with the first and fifth toes reduced in size, giving them an appearance similar to those of a rabbit. The fur is dark brown to buff-grey over the upper parts of the body, becoming paler, sometimes almost white, on the underparts. Without genetic analysis, the bunny rat can only be reliably distinguished from its close relative, the

The bunny rat is a heavily built rat-like rodent, with a total length of 20 to 27 cm (7.9 to 10.6 in), including the 7 to 10 cm (2.8 to 3.9 in) tail. Adults weigh an average of about 80 g (2.8 oz). The body is covered in long soft hair, and the tail is also hairy, ending

Bunny rats can reach population densities of 10–15 per hectare (4.0–6.1/acre) in ideal conditions. They are common prey for owls, and are thought to have a maximum lifespan of 15 months. They breed between
September and March, but most commonly in the spring, and give birth to litters of up to eight

Bunny rats feed almost entirely on grass, and can consume a mass of vegetation equal to their own body weight in a single night. Although primarily nocturnal, they may also be active during the day, depending on the weather, and spend most of their waking hours feeding. They sleep in tunnels, which

are about 4 to 7 cm (1.6 to 2.8 in) wide, and have multiple entrances. In many cases, they may co-opt tunnels dug by other rodent species, and may even share them with the original inhabitant.
