Is there a very large mouse hiding in that ginormous wedge of cheese? I think your cat needs to find out. And if not, it might be just the place for a cozy snooze. Assembled, the Monster Cheese Wedge Box is approximately 22 inches long, 16 inches wide, and 10 inches deep. Holes are approximately 6 1/2 inches in diameter. The box has hook-and-loop dots which enable it to be disassembled for flat storage, and then reassembled again.
