oh that will make it much easier. i was planning to spot clean the fecal matter and leave urine and stir it into the dirt, like you. just didnt know if my ph levels in the substrate would be strong enough to break it down without a cleaning crew. so i started looking up spring tails and isopods which my wife would probably hate in the house. i'm thinking if they are needed, a cleaning crew that is, maybe red worms wouldnt be that bad
