On Sunday 6-year-old Rivers Hobbs, was ambushed by a mountain lion in Texas’ Big Bend National Park. Rivers and his parents were walking from a lodge back to their hotel room when the lion pounced on the boy, slashing him in the face.

Luckily the boy’s father was able to knock the cat off Rivers by stabbing it repeatedly in the side with a pocket knife, according to

The boy survived, but needed 17 stitches on the side of his face.

“It sneaked up on me,” said Hobbs.

Another family who had also been attacked warned them about the lion earlier in the day. They were originally going to camp out, but after hearing the news, decided it was best to go to the hotel. Park Rangers said the animal will be killed if located.
