Cats purr. The sound is made by using vocal folds and the muscles of the larynx, according to Wikipedia. By alternating, the folds and the muscle dilate and constrict the glottis quickly – this causes air vibrations when the cat breathes. Complicated process for a very well-known sound in the animal kingdom.
Cats purr most often when they are happy or content. They may also purr when they want something – like food. It is also believed that cats will purr to help get relief and to heal. Sort of like when a baby sucks its thumb – it just helps soothe and calm them. You may have to turn up the volume to hear this kitty ‘humming’!
