I can only imagine. I wondered about the roll up thing too. But for now your puzzles are solving the problem perfectly. Well almost perfectly - Nightshade can still hit the scramble button and move individual pieces.Blossom was no help at all on the Christmas puzzle! She mostly left it alone, but on the days she took an interest, it was cat-astrophic. I need to get one of those felt roll-ups for packing away a partially completed puzzle.
