So, Mona's cleverness with the door knobs became less cute. Emma, Lilah's snake, has been staying in one of the bedrooms. Mona 'broke in' last night and liberated the snake.Emma is still on the run. She's too big for Mona to eat, and I'm not sure who would win, actually. But no carcass, no snake.I switched out the four inside door knobs that weren't lockable this afternoon.
