If Humans Could Adopt Any Animal Trait #1 Purring

Image courtesy of designfart.blogspot.comYou bump into an old friend on the street, you are delighted to see each other, you smile, laugh, share some news, how great would it then be if you could purr your contentment. Yes, my first choice in the adoption of animal traits to enhance a human is . . . . purring.

And here’s why.

Purring would make for a good night’s sleep. I am often lulled to sleep by the purred duet of two of my cats and I find it immensely restful and calming. I’ve found it’s the best remedy for sleepless nights, far better than the recommended, but ultimately useless, herb and tea concoctions. Imagine then how useful it would be if we could purr ourselves to sleep.

Purring would help those awkward social interactions; that’s because purring in cats may release endorphins into the bloodstream. Endorphins lower our stress levels, so for us humans who sometimes find real life a little difficult and uncomfortable, being able to launch into a purring session would lessen our fears and create an aura of calm. How great to have that as an inbuilt mechanism.

Purring could help us heal and keep us healthy. Studies in cat purring (yes, these do exist) have shown that purring lowers blood pressure and alleviates depression. There is also the suggestion that purring promotes the healing of bones due to purring being at the same sound frequencies (25 – 150 Hz) proven to aid bone healing. We all know that cats purr when they are injured, so that’s highly suggestible of a healing technique. A purr a day would keep the doctor away.

Random Purr Facts

Cats purr around 25 dB.  This is louder than rustling leaves (20 dB) and quieter than library noise (40 dB).

Scientists have yet to discover exactly how a cat purrs. Ideas put forward are having a secondary set of membranes near the vocal chords or the vibration of blood vessels in the throat and chest.

Domestic cats purr when breathing in and out. This is distinct from the miaow that occurs only on the outward breath.

Other species in the Felidae family that purr: Bobcat, Cheetah, Eurasian Lynx, Puma, and Wild Cat

Big cats from the Patherinae subfamily exhibit a purr-like sound, but it’s not true purring:  Lion, Leopard, Jaguar, Tiger, Snow Leopard, and Clouded Leopard.

    Nice! I was thinking it could be handy to have a monkey tail….

      Excellent. Be handy to carry an extra bag, call a taxi when your hands are full, hold on in the underground. Great idea – endless uses. 🙂
