* Groom themselves: The papillae act like a comb, helping to remove loose fur and debris.
* Lap up liquids: The backward-facing spines create a suction effect, allowing the cat to easily drink from a bowl or puddle.
* Consume meat: The papillae help to scrape meat off bones and tear through tough tissues.
The papillae are also responsible for the "rough" feeling of a cat's tongue.
