Remix

Prompt
Yes, cats do have spines on their tongues! These spines are called papillae, and they are: Hook-shaped and made of keratin, the same tough protein found in human fingernails. Extremely rough to the touch, which helps cats: Groom themselves effectively by removing loose fur and dirt. Strip meat from bones when eating prey or food. Lap up water using a rapid, curling motion of the tongue. If you've ever been licked by a cat, you've felt just how sandpapery their tongue is—that's those keratin spines at work!
