Bladder of steel?

Theo is curious about the potty so on a whim (you know, one of those trips to Target where you find yourself buying things NOT on your list) I picked up this froggy potty. Theo had just downed a cup of milk and we figured he'd be primed to make a little pee. Well, we waited and waited....... and waited some more. We fed him all sorts of treats to get him to stay there. Nothing ever did end up happening. Oh well.
