I think the second best toy in the world for cats is the cardboard box. Bastet and Zaicha just love them. Its a real battle between the two as to who gets to sit in the box first. its also a race at who gets the feather stick (called a cat tickler in Australia) and the fish on the pole. But they also enjoy having a nap in them so for all those fur parents out there that need a little time out from kitty capers the simple cardboard box is the way to go!
