Sometimes if they do it all at once, you get lucky and they manage to wrap all the poop and urates neatly in the shed skin. It only happened once, but I'm hopeful. My big normal male did everything and made a little rolled up parcel out of his shed, right in the corner where all the pee was.
On the down side, he's a big water drinker and can pee 100+ grams in weight with no warning.
