Some time ago I made a natural sunning oil with black walnut oil and other good stuff. A squirrel nabbed the entire bottle with the cap between its teeth, ran into a
fence, tried to climb over, dropped the bottle, scurried back down to try again, by which time I came near
enough that it ran away. I thought. About 5-ish minutes later the squirrel snuck up again, grabbed the cap apparently better than before, managed to get the bottle over the fence and was gone. A+ for diligence! :) I got an A- for not having considered the possibility.
