That's why you spot clean every day or two, and change all the litter every week. Putting lots of hay on top of the shavings will even allow the droppings and urine to fall through to the bedding so the piggies don't have to walk on them, and prevent the shavings from sticking to their veggies. Grids simply aren't acceptable for piggies to live on.No matter how huge a cage can be, it can never be as big as the "wild" and there isn't the natural bacteria to decompose their waste ... so, I guess that if I do not want a sick GP, I really need to keep them clean.
