Training rats to detect explosives in minefields
A rat and a cat are seen in a cage at a police station in Bogotá, Colombia.
The Colombian police force has been experimenting with training rodents to
detect explosives in minefields. The process would take advantage of a rat´s
acute sense of smell and low weight, which would allow them to find mines
without activating them. The cats are included in the training to help rats
become used to possible predators.
