Cougar Mountain Zoo, Issaquah, Washington, October, 2011, Taj, a 370-lb. Bengal Tiger responds to toddler pressing her hands on the glass of his cage with obvious feline gestures of affection.

At zoos, one sometimes sees a side of large, dangerous animals which is essentially identical to the behavior of your pet at home. One day, at the Chicago Zoo, I watched with amazement as a White Rhino the size of a delivery van manifested recognizable ecstacy while a teenage zookeeper stroked her back with a large push broom.
