WHY DO CAT TONGUES FEEL ROUGH?

WHY DO CAT TONGUES FEEL ROUGH?
Cat tongues are rough because they are
covered with hundreds of tiny, backward
facing hooks called papillae, which they use
to scrape meat off bones and hair off hides.
These papillae also help the cat drink, acting
like tiny cups to help hold water on its tongue.
