The sound of two lynx fighting is infectious. By this morning, it had more than 11 million views, and those who captured the video have been getting calls from around the world.
Ed Trist and his girlfriend, Nicole Lewis, were out checking minnow traps over the long weekend, when they captured two lynx fighting near Dinorwic, east of Dryden.
"So, I posted it to Facebook, expecting my friends would really enjoy it, but after the first hour it had 10,000 shares. By morning it had more than a million," said Trist.
"It's absolutely crazy. I've had calls from the BBC in England and Australia. I can't keep up," he said.
