Giant pouched rat

The giant pouched rats (genus Cricetomys) of sub-Saharan Africa are large muroid rodents.

Their head and body lengths range from 25–45 cm (10–17.5 in) with scaly tails ranging from 36–46 cm (14–18 in). They weigh between 1.0 and 1.5 kg (2.2 and 3.3 lb).

Giant pouched rats are only distantly related to the true rats, although until recently they had been placed in the same family, Muridae. Recent molecular studies, however, place them in the family Nesomyidae, part of an ancient radiation of African and Malagasy muroids. The name "pouched rat" refers to their large cheek pouches.

The species are:

Females have been said to be capable of producing up to 10 litters yearly. Gestation is 27–36 days. The animals generally have between six and eight nipples. One to five young are born at a time.

The animals are nocturnal omnivores, and feed on vegetation and small animals, especially insects. They have a particular taste for palm nuts.

In many African countries, giant pouched rats are valued as an important food item.

They are easily tamed as pets, but were associated with an outbreak of monkeypox in the USA in 2003, and have since been banned from importation to the U.S.
