baby MASTOMYS is born!

Welcome to the world, MASTOMYS! It is celebration time in APOPO's rat kennels today for the birth of baby MASTOMYS and its two siblings. MASTOMYS belongs to the species Cricetomys gambianus, commonly known as the African giant pouched rat, which are often born in litters of 2 or 3. APOPO's breeding program ensures that prospective parents of our future heroes are carefully handpicked to deliver healthy, happy and high-quality rat babies.  A successful breeding program increases the likelihood of delivering excellent HeroRATs to detect landmines and tuberculosis.


APOPO's early experiences demonstrated that rats that grow up in the organization's kennels are easier to train and are more effective scent detectors. Since many rats are needed for mine action and TB detection operations, APOPO's research and development department is constantly working on ways to optimize the breeding program. Before placing rat couples in the breeding cages, the APOPO staff closely monitors the acceptance behavior of the animals in the introduction cage. Female rats either reject or accept a prospective mate in this cage and in cases of clear acceptance, the rat couples are placed together in the breeding cages.  Crucial information such as the best timing for the female rats and the fertility period of the male rats go a long way in improving the productivity of the breeding colony. APOPO's breeding program also ensures optimal care, feeding and medical attention to aid the overall welfare of the animals and subsequently improve the quality of rats available for training.
