I hate pooping in the dark :-) I think one of the other comments probably tracks a bit more, good cats have an instinct to burry it and then scratch up the whole area so it’s less obvious they hid something.
Honestly crocodile box isn’t far off either. The bigger the box, the less chance anything winds up outside. Every time we got a bigger box it made cleanup a bit easier, the corner box fit the bill and has 2 high sides so no pee hits the wall :-)
