Mastomys


Mastomys is a genus of rodent in the family Muridae endemic to Africa. It contains eight species:
The multimammate mice are found in most parts of sub-Saharan Africa. Their head-body length is between 10 and 15 cm, their tail length is between, and their weight varies between, depending on the species. Domesticated multimammate mice are heavier on average, weighing from. Mastomys species are omnivorous, and can live up to four years.
Systematically, they were long placed in the genus Rattus. Later they were placed in the genus Mus and then they were placed in the genus Praomys. Today, molecular research has discovered that they are a genus of their own and that they are closely related to Praomys. They are also more closely related to Mus than to Rattus. The dwarf multimammate mouse was formerly classified in this genus, but has now been moved to its own genus.
