So a thought occurred to me last night, right before bed.

Why do humans appear to be the only species that require an additional item after they expel waste? Yes, boys and girls, I’m talking about toilet paper!

Cats just drop their presents in the litter box and walk away. Dogs do their business and then go about their business. Birds are well-known as the animal equivalent of bombardier’s.

To the best of my knowledge, no primate uses leaves to wipe their behinds after they poop. So that would discount the evolutionary aspect of it. Chimps might use their waste as a weapon and fling it, but I’m talking about the necessity of using other material for hygiene purposes.

No-where else on this planet do you find another species who behaves in this regard.

Yet, I hardly feel people would choose this as our “claim to fame”. =/
