If a cat ever licked you, you may notice the rough, sandpaper feel of a cat’s tongue. That’s because a cat’s tongue serves two purposes. First, the tongue needs to help the cat clean and groom its fur. Second, the tongue needs to help cats lap up water.
Surprisingly, scientists had to use high-speed photography to capture how a cat drinks water using the rough surface of its tongue to pull up water before clamping down on this water to drink. This seemingly gravity-defying process makes a cat’s tongue unique among all types of animals.
