Interesting article about squirrels in the New York Times reveals that:
*Squirrels greet each other with a mutual nuzzling of cheek and lip glands that looks decidedly like a kiss.
*A squirrel's tail is a serves as a thermoregulatory device, in winter helping to shunt warm blood toward the squirrel’s core and in summer to wick excess heat off into the air.
*Squirrels can rotate their ankles 180 degrees, and so keep a grip while climbing no matter which way they’re facing.
