I know what you mean about Ritz going crazy when someone scratches her "tickle spot"! Vinny reacts by arching his back and purring when you scratch him there, and he also loves having the sides of his hind legs rubbed. When you do this he throws himself onto his side, digs his claws into the carpet in ecstacy, and drags himself along the carpet. At the same time, he extends the toes on his hind feet as far as they'll go, and it looks really hilarious! He particularly enjoys his "butt rubs" late in the evening! lol
