Tongue

A cat's tongue is very rough. Do you want to know why? Well, their tongue is made of little micro spike-like things. This is great to scrape meat off bones and grooming themselves. That's why it feels so rough when the cat licks you. Their tongue is also made to make a cup shape. We can't make our tongue shaped like a little cup, and that is why we drink differently than cats. Cats scoop up the water, put it in their mouths, and swallow it. To a cat it's easy, to us we might say "Oh man, I spilled!"
