Scientists Don’t Understand Purring Cats
Cats purr when they’re happy, comfortable, sad, or frightened. Most of the time, purring is said to send out waves of calmness or when the cat is feeling content. The list goes on, and because of this, scientists still don’t fully understand when and why cats purr. Tigers and lions are unable to purr, even though they’re considered big cats, while cougars, bobcats, and lynxes can purr. While the reason for a cat’s purr remains a mystery, scientists assume they engage in purring as a soothing mechanism and to encourage bone growth. Their purrs range at a frequency between 25-150 Hz, which helps improve bone density and promotes healing in their bodies. Their cute rumbles have much more purpose than sounding like a cute grumble (North Care).
