We found some of these a bit messy for in the house, so used biscuits that you can only get in by squeezing the kong to make the hole oval. Took Hook about 2 weeks to work out to lay on his back with the kong in his mouth and squeeze! Truffle never has worked it out. Otherwise any assortment of left overs, including fruit and vegies.
