John when you play with Gracie, stay away from her tail/bum and her wings. When I tickle my grey, I only rub/pet her feet (it is always good to be able to handle your grey's feet in case they need some foot care) and scratch the top of her head and under her chin. Never for very long. If Gracie gets rough tell her to "be gentle" (I say this to Ana Grey as I gently stroke her and she understands what gentle means). If Gracie won't calm down, stop playing for a while and just talk to her.
