Who needs all those expensive supplements to keep you on top of your game when you can rather simply get some osteophagia in your life?The wildlife volunteers and I encountered this female giraffe in Ithala Game Reserve supplementing her diet by sucking on a bone. Our first clue to something unusual happening, was watching her trying to toss something that was too big to chew from side to side in her mouth – similar to when you see the tough guys in old movies chewing on a large piece of tobacco, moving the ball from cheek to cheek. It wasn't very ladylike at all and then out popped the bone.
