Sometimes cats are targeted as rude and insensitive. But actually, some of them are incredibly well brought-up. In this video Leon the cat opens five doors to let himself out. The feline takes a while to get moving, but once the first door is opened the other four are effortless for this fella. Leon was found at a market on the Macedon streets and used his street smart skills to open doors himself, according to his owner Marjan Kirovski.
