1. What Is a Cat’s Purr?
A cat’s purr is a distinct vocalization characterized by a low, rhythmic sound and a subtle, soothing vibration felt through the cat’s body. Unlike meows or hisses, purring falls within a unique frequency range—typically between 25 and 150 Hertz (National Geographic). This specific frequency, combined with its continuous, oscillating nature, sets the purr apart from other feline sounds, making it instantly recognizable and truly remarkable in the animal kingdom.
