The Cat's Purr

Cats have been domesticated for nearly 10000 years. They are currently the most popular pets in the world. Cuddling up with a cat is certainly a relaxing experience, but there is more to it. Cats create purr vibrations within a range 20-140 Hz, known to be medically therapeutic for many illnesses. Petting a purring cat calms down your nerves and thus lowers stress.
