In the world of medical history, “snake oil” is a worthless alm schlepped by traveling salesman trying to make a quick buck.
In the squirrel world, though, snake oil is far more precious. Some very crafty California ground squirrels (who live all over the West) have been discovered chewing on the molted skin of rattlesnakes, then smearing the essence on their fur. Voila! Presto! They now smell like intimidating snakes! That’s one smart way to stay out of a snake’s belly!
