MILL CREEK, Wash. -- Department of Fish and Wildlife agents said they were forced to capture two black bear cubs found near a campground after their mother was struck and killed by a car, reported KIRO 7 Eyewitness News.

Wildlife officials said the mother was hit and killed on Saturday near Interstate 90 after she had been in the area of the Denny Creek campground, where people had been leaving food out and coolers unsecured.

After their mother was killed, wildlife agents said the cubs returned to the campground looking for food.

Agents said they were able to easily capture the two cubs in the area Monday night by leaving doughnuts out, which caused the cubs to come down from a tree and head directly for the food.

Officials said the cubs could not survive on their own.

Wildlife agents said such incidents could be prevented if people at campsites would be more responsible about leaving food unsecured.

"The bottom line is this was a human-induced problem," said wildlife agent Kim Chandler.

The bear cubs were transferred to PAWS in Lynnwood where they were examined. The bears will undergo up to a year of rehabilitation and isolated in a recreated wildlife setting before they can be released.

The veterinarian at PAWS said the male cub weighed 40 pounds, the female weighed 25 pounds, they had no injuries but were both hungry and feisty.

PAWS has cared for more than 50 bears over the past 20 years.
