The purr of a cat. It’s the sound that makes you smile and think all is right in his world.
It’s the most mesmerizing sound, but no one is certain exactly why cats purr, though there are a number of good guesses. The obvious observation is cats seem to purr when they’re pleased and feeling good. But that’s not always the case: some cats also purr when they’re hungry, injured, or frightened.
Kittens learn how to purr when they are a couple of days old. Veterinarians suggest that this purring tells ‘Mom’ that “I am okay” and that “I am here.” It also indicates a bonding mechanism between kitten and mother.
Cats purr by using their larynx and diaphragm muscles, both as they inhale and as they exhale, although just how the central nervous system generates and controls those contractions isn’t yet understood.
Many suggest a cat purrs from contentment and pleasure. But a cat also purrs when it is injured and in pain. The purr, with its low frequency vibrations, is a “natural healing mechanism” linked to the strengthening and repairing of bones, relief of pain, and wound healing.
