Multimammate rats, scientifically known as Mastomys, are small rodents found primarily in Africa. They are named for their distinctive feature of having multiple mammary glands, which allows females to nurse large litters. These rats are adaptable and can thrive in various habitats, including grasslands, savannas, and urban areas. These rodents are known for their rapid reproduction and can reach sexual maturity in just a few weeks. Multimammate rats play a significant role in their ecosystems, serving as prey for various predators and contributing to seed dispersal. They are also studied for their potential as disease vectors, particularly in relation to Lassa fever.
