By now we know virtually all there is to know about the wild kingdom. Whole libraries house documentary footage of almost every moment from the lives of almost every member of every phyla in every far flung stretch of humid reeds. But in all that footage we see no evidence of any wild animals itching.

We itch.

Our domesticated furry friends itch perhaps more than anything else in a given day.

So why don't they--living out there amidst whole minions of living, air-borne irritants--itch?

Who's fooling who? I want answers.
