I have made camp for one or more nights in a pristine wilderness. At a suitable distance from camp, I have dug a nice cathole and done my business. Now it's time to sleep. Should I close my cathole and dig a new one tomorrow, or do I leave open and reuse my cathole and wait until I depart before closing it? Maybe an open cathole is more likely to attract animals, but multiple catholes leave more traces than just one.
