Sweet potato follies. Go read the whole thing, it’s howlingly funny.
The two present beasts are not at all interested in human food. Riot sniffs right past it, and Puck actively avoids me when I’m eating something, no matter what it is. Our late Fox, however, was a human food vaccuum. It wasn’t good for him so we tried to keep him away from it, only to have him snatch a piece of cheese, or a melon rind, or a beef stick right out of our hands.
I once made the mistake of leaving bags of groceries on the floor while I put things away, and I turned my back for a second only to notice Fox sneak into the bag, pull out an apple that probably outweighed him, sink his little fangs into it and take off running.
We never tried a sweet potato with him, though.
