Rafiki likes to practice the art of decoupage. She will unroll toilet paper or steal tissues and place them in the toilet. She prefers tissue or cotton balls to TP because TP falls apart too easily. When it is a soggy mess, she will retrieve it. So far, she has mainly placed piles of toilet-soggy-paper in our bedroom and den but has also managed to stick a few pieces to the bathroom walls. And yes, training the silly humans to keep the lid down is best but......she is starting to learn how to lift the lid so that may not work for much longer.
