Eeeeew. I suggest using food bowls you can hang onto the grids so the pigs don't get their butts up there. Like the bird food bowls jdomans showed.
My pigs don't pee into their bowls. I find the occasional poop but I find the occasional poo everywhere anyway, so I don't worry. At least the food doesn't get spoilt.
