An excerpt from Becoming a Tiger: How Baby Animals Learn to Live in the Wild, by Susan McCarthy.

Karen Pryor describes an incident in which her daughter spent an hour teaching her small poodle to jump into a child’s rocking chair and then make it rock. She rewarded its efforts with bits of chopped ham. At the end of the lesson the poodle jumped down and a cat who had been watching jumped into the chair, unbidden, set it rocking, and looked up for her ham.
