The multimammate mice (also called multimammate rats, african soft-furred rats, natal-rats or african common rats) are found in most parts of Sub-Saharan Africa. Their head-body length is between 10 and 17 cm, their tail length is between 8 and 15 cm and their weight varies between 20 and 80 grams, depending on the species. Domesticated multimammate mice are heavier on average, weighting from 60 to 160 Grams. Males are much larger and heavier than females. They weight between 80 and 160 Grams. Females are smaller and lighter build, normally weighting between 60 and 110 grams. Males also have a much more shaggy fur and a bull neck, that is starting to grow at the age of six month (African soft furred rats are fully grown at the age of 8 months). Females have a more silky fur and a more petite build. Some African soft furred rats are very tame and cuddly, while others are very skittish and sometimes bite when handled. Males on average are more relaxed and cuddly than females. Mastomys are omnivorous and can live up to four years. A female can have as many as 12 litters a year.
Systematically they were long placed in the genus Rattus (referred to as Rattus natalensis). Later they were placed in the genus Mus (referred to as Mus natalensis) and then they were placed in the genus Praomys. Today molecular research has discovered that they are a genus of their own (Mastomys) and that they are closely related to Praomys. They are more closely related to Mus than to Rattus. All the domesticated multimammate mice are hybrids between the natal multimammate mouse (Mastomys natalensis) and the Southern multimammate mouse (Mastomys coucha).
