If you have pet cats at home, you’ll be familiar with their rough tongues. While most animals have smooth tongues, cats actually have barbs on theirs and the bigger the cat, the bigger those barbs. Lions, tigers and cheetahs have large barbs designed to help them tear meat and hide of their prey while they eat.
These are so effective that a lion could draw blood from skin in just a few licks! These barbs can also help them keep clean, assisting in removal of dirt when they groom themselves.
