I sometimes wonder what Pokemon do when they do their 'business'. Do owners/trainers pick up after them? Or do they just leave it there on the sidewalk. Do pokemon use toilets?

Like imagine Meowscarada squatting down laying a fat stinker only for the poor trainer to pick it up in a plastic bag. Then carrying it around until they find a good way to dispose of it. Kind of explains why some of the NPC's in the game hate pokemon.
