Cats like toys, but they most often prefer the cardboard boxes that toys come in. If your cat prefers cardboard over real toys, then you might consider a cardboard scratchpad that doubles up as a board game.
With pockets and balls, this scratchpad looks like a billiard table. Now cats can smack a ball around or scratch the pad to rip it to shreds just for the sake of destroying something. With a combination game/scratchpad, your cat won’t have any excuse to be bored now, unless it’s to find yet another way to drive you crazy.
