My Elvis is a pretty big boar. I like to say he's "big boned." Anyway he often uses his hind foot to scratch his cheek/neck/ear area. More than once I've seen him furiously scratching and then lose his balance and roll over onto his back. He rights himself pretty quickly. Last time he actually rolled all the way over onto his feet again. Full 360. It is too funny. Do other pigs do this -- or is my Elvis just a bit more clumsy than most??? lol
