That is too funny! When Kaji and I still lived in Irvine, we had shower doors instead of a curtain. He would scratch and scratch until I opened the door enough for him to see me so he knows I wasn't trying to get away, or because he's a peeping tom. Eventually he learned to open the door all by himself, and he would always smile because he was so proud of himself. Well, I was at work and my roomie was alone with the dogs, hers and Kaji. Kaji was pacing so she thought taking him to the bathroom with her and Danger (her dog) would be ok. To her surprise, Kaji opened the shower door wide open and scared her! She never took him into the bathroom with her again.
