He then had a thought: Why not use rats? They’re cheap, possess remarkable olfactory systems, and are social and intelligent animals, contrary to popular belief. And so Weetjens founded APOPO, a nonprofit rat training organisation in Tanzania, home to the largest and longest-living rat species.
Some of the African giant pouched rats trained by APOPO can live up to a decade, while typical domestic rats typically live only two to four years. This longer lifespan, along with their exceptional sense of smell, has made the African giant pouched rat of invaluable service for many years in various projects. Previous generations of these giant rats have successfully assisted in landmine detection, which was Weetjens’s initial goal, and in detecting tuberculosis.
Now, the rats have been trained for a new…
