A 2006 University of Cambridge study found that meerkats teach pups how to hunt by first introducing them to dead prey, then to injured prey; when the pup is ready, the adults present them with live prey. “There were clear post-provisioning costs involved in feeding pups live prey,” the researchers wrote. If the prey escaped, the adults were able to recapture it only about 26 percent of the time. “On around 7 percent of occasions, helpers further modified the prey before returning it.”
