Doozy Cat had very firm ideas about her feeding schedule...whenever she wanted food she got it. Doozy got fat, and Karen and Dave put the kitty on a diet. Kitty didn't like the diet, so evil humans were no longer allowed to sleep. She started with scratching the walls at night, sort of like that chalk board sound. We got a water bottle and started using it. Doozy cat took her scratching around the corner, "ha, silly humans, that water can't touch me". We learned to ignore it. Doozy learned new tricks....pull the window shade out, let it slap back, pull it out again, and again until someone throws a book. "Ha....woke you up!" Then she moved on to tossing things off my dresser. She would jump up and then casually toss the Carmex on the floor, then the watch, then the alarm clock and then whatever. The final step in the waking the people process was stepping on the answering machine buttons and playing back messages in the middle of the night. Finally she got banished from the bedroom....we had her 19 years and I still miss my Doozy Cat.
