why do cats have spiky tongues

John

I've always wondered why my cat's tongue feels so rough when she licks me. It's covered in tiny, spiky structures that almost feel like sandpaper. At first, I thought it was just my cat, but then I noticed other cats have the same texture. What's the purpose of these spiky tongues? Do they help with grooming, eating, or something else?

Cats have spiky tongues due to tiny, backward-facing structures called papillae. These papillae are made of keratin, the same material as human fingernails. They help cats groom themselves efficiently by acting like a built-in comb, removing loose fur and dirt from their coats. Additionally, the papillae assist in scraping meat off bones when eating, making them highly effective hunters and eaters.

The spiky texture of a cat's tongue serves multiple functions. Primarily, it aids in grooming by distributing saliva evenly across their fur, which helps with cleaning and temperature regulation. The papillae also help cats drink water—they curl their tongues backward to create a ladle-like motion, and the spikes help pull water into their mouths more effectively.

I heard that the spikes on a cat's tongue can also help them catch prey. Is that true?

Elizabeth

Anthony Yes, that's correct! The papillae help cats grip and tear meat more efficiently, which is especially useful for wild cats hunting prey. The rough texture allows them to lick bones clean and hold onto slippery food.

Does the roughness of their tongue ever cause problems, like hurting their skin when they groom?

Jack

Theodore Generally, no—cats' skin is tough enough to handle the roughness. However, excessive grooming can sometimes lead to irritation or hair loss, especially in stressed or anxious cats. But under normal circumstances, their tongues are perfectly adapted for their grooming needs.
