Bears, wolves, coyotes, cougars, OK- but BEAVERS?

"I've never tried to fight off a 35-, 40-pound beaver," he said. "This was one of the biggest beavers I've ever seen."

I couldn't guess as to its weight, but when I was a boy I once saw a beaver five feet long. I was glad that we didn't go near that branch of French Creek very often.
Then again, there's a 'silverback' woodchuck on my parents' property that's two feet tall. That is - when he sits upright, the top of his head is two feet off the ground. We nicknamed him "Sasquatch."
