LOL! Cody used to do that to Remi! Granted, Remi is 100% Meanness poured into a cute puppy package, so usually Cody did this after he was tired of Remi's antics.
Remi would be taking a two minute rest break from attacking/pouncing/playing with Cody. Usually he would rest on the cushion by the window. Cody would just calmly walk over to the window, circle around by Remi, sit right on his head, and look at me with his forehead wrinkled so as to say, "Mama, you know you'd have done the same thing if he was going after your dangley-bits, if you had them."
