Jeopards: They look a little bit like a cross between a jackal and a leopard.
For the last hundred thousand generations, selection pressure has been training them to cull the grazing herds they hunt. The jeopard pack nips and bays at the larger, healthier herd members, and separates them from one or two smaller, less vital members of the herd.
Jeopard casualties are rare. Herd are limited to "enough for this week's meal." Other herd beasts accept this sacrifice. Nonsapient, they place little value on the lives of individual herd members. The jeopards may not be sapient, but they are not stupid. They think, and they learn 2006-08-20.
