Wolves killed two calves during separate Lassen County incidents this month in what wildlife officials are calling the largest wolf attack on livestock since the predators returned to California.

The yearling cattle were killed by wolves on private land in western Lassen County, and three other cattle were found with tooth scrapes and other injuries, according to investigative reports from the California Department of Fish and Wildlife.

A ranch hand discovered the first attack July 13 after spotting “a wolf feeding on the carcass of an approximately 550-pound yearling cow,” which was reported to state and federal officials, a state report said.
