Be careful when somebody's knocking at your door
(via), a stunning story:
Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door. They believe the 35-stone brown bear probably learned the trick while nudging a door to get it to open.
Experts speculate the nudging was mistaken by the owners for knocking and that the bear, pleased by the outcome, repeated the tactic. The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door.
Mum Nevenka Loknar said: "We jumped out the window as he came in through the door and raided the kitchen the first time. "I opened the door and saw him standing there and I didn't believe my eyes at first, then I ran for it as he walked in as if it was the most normal thing in the world. "Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door.
"The bear is so intelligent it's incredible. We've tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn't be surprised if he knew how to use wire cutters."
An animal life hack!
