Next time you get something that comes in a large cardboard box, cut the top off, and the cut a "door" in one side, and "windows" in the other sides, and then up-end it on the floor. The cats will go crazy. The last time my friends and i did this (they had four cats) the cats went wild. They would run in the box and peer out, then run out of the box and peer in. Any cat in the box was treated as though he were an unknown cat and an interloper.
I've got a long low fedex box sitting in the middle of my living room right now. About 3 feet long, 1.5 feet wide, and 6 inches high.
It took them about 15 seconds to find the box and move in. Now, 3 days later, the "roof" is all crushed in, because one will get deep inside the box, and the other will cause a mine shaft collapse by pretending to be a huge boulder landing on top of the entrance.
The trapped miner then has to dig his way out.
