The other night, my partner got up in the morning to find Sleepers
lying outside her bedroom door, apparently having been left there by one or more of the cats.
Several pairs of tiny holes in the bag and instruction sheet confirmed this theory. Either it took several tries to pick up in the first place, or the move happened in several stages. In either case, the cat(s) extracted it from a bag full of games and carried it up a flight of stairs.
Sadly, due to feline skill at operational secrecy, there's no picture of a cat posing with the game in its mouth or anything like that.
Anyway, I'm pretty sure this couldn't have happened were the game not lightweight AND compact AND in such flexible packaging, all much more so than other board games. So basically nestorgames are ideal for cats.
(Except for playing them. Probably?)
