"She jumped it," the boy's father, Kevin Bromley, told the CBC.
"I think any mom would do that. It's that selfless love," he said.
The boy suffered minor injuries to his head, neck and arm. He was airlifted to a local hospital for treatment and released Saturday, the network reported. Chelsea Bromley sustained minor injuries to her hand.
It’s not out of the ordinary to catch a glimpse of the big cats on the island, but the behavior of the animal that attacked the boy is unusual.
Authorities tracked down and killed both cats, according to The Cowichan Valley Citizen.
"The cougars were both very emaciated, very skinny and in poor overall condition, very light for their size, inspector Ben York told The Vancouver Courier.
“We don’t know what might have caused that,” but York said a necropsy is being conducted on the animals to find out if they were diseased or injured.
He told the newspaper the young cougars may have been orphaned and left to fend for themselves.
The animals are usually quiet and elusive and attacks on people are extremely rare, according to wildlife experts. The Colorado Division of Wildlife reports fewer than a dozen fatalities by mountain lions in North America in more than 100 years.
