Treat balls are also great for keeping them occupied. It's a plastic ball with small holes on the sides. There is space inside to insert treats and they fall out if the ball is rolled. I think the Kong company makes a red one - lasts forever (well, until a staffie gets it
)
Cash loves treat balls and he will play much more with those than a kong. I also give them raw bones and hooves as well as organic ostrich chews that I get from a local pet store.
I just want to mention, a completely full treat ball didn't stop Cash from learning to open the fridge!
