Magawa was in good health and spent most of last week playing with his usual enthusiasm, but towards the weekend he started to slow down, napping more and showing less interest in food in his last days. Magawa had recently celebrated his birthday in November, reaching the grand old age of 8.”'Hero rat' wins gold medal from UK charity for hunting landminesThe tribute said that Magawa had left a “lasting legacy in the lives that he saved,” adding: “All of us at APOPO are feeling the loss of Magawa and we are grateful for the incredible work he’s done.”Read MoreMagawa, who retired last year, is APOPO’s most successful “hero rat” to date, the organization said. “His contribution allows communities in Cambodia to live, work, and play; without fear of losing life or limb,” APOPO added.African giant pouched rats are intelligent and easy to train — Magawa began training from a young age. He was born in November 2013 at Sokoine University of Agriculture in Tanzania, where he learned how to find explosives using his amazing sense of smell, APOPO said. Three years later he moved to Siem Reap in Cambodia, where he began his career.APOPO trains the rats to detect the scent of the explosive chemicals used in landmines and point them out to their handlers.Magawa’s work has helped the organization clear more than 225,000 square meters of land in Cambodia, where decades of conflict have left the landscape strewn with dangerous unexploded devices.
