Here's one freaky sound you don't want to hear when you're alone in the woods.
Nicole Lewis and Ed Trist captured the following footage May 18 in northern Ontario.
As you're about to see, this rare encounter was both amazing and terrifying.
The two, as well Trist's daughter, were traveling along a logging road on their way to fish near Avery Lake, just east of Kenora, when they came upon the pair of cats.
It was a once-in-a-lifetime experience for this lucky threesome, as this video has been viewed more than 10 million times so far.
