Connoisseur of castoffs, gourmand of garbage, this litter literati is a begging bandit who will stop at nothing to liberate your leftovers!
While they may love it, litter is not good for this critter. During the long, cold winter months in Rocky Mountain National Park where this was taken their energy reserves will run low if they've been eating human food instead of their normal fare.
So do them a favor and don't feed the litter critters, even if they beg you like this!
