Scientists changed how zoo lions eat. Their wild side came out

Giving zoo lions whole carcasses on a feast-and-fast schedule appears to bring out more natural behavior. The lions spent nearly three times longer feeding, engaged in more tearing and manipulating of food, and rested more heavily after meals. Their activity then increased gradually during the fasting period, closely resembling the rhythm seen in wild lions.
