Who says Tom and Jerry can't be friends? For the past year, a special Colombian police unit has been locking rats in cages with cats as part of a project to train the rodents to sniff out the more than 100,000 landmines planted mostly by leftist rebels across this conflict-wracked Andean country.
Bringing the rats face to face with an enemy allows them to stay more focused once they are released, veterinarian Luisa Mendez, who's been working with the animals for two years, told The Associated Press.
The rodents are taught to freeze in front of mines, but had difficulty staying put for fear of being attacked by predators.
The rats' success rate in mine detection is 96 percent. Unlike dogs, the rats weigh a lot less and therefore don't trigger explosions.
