Hi all, We have a new run that we filled with sand. Do any of you have runs with sand? How do you clean up the poop? I thought I could just rake it out, but it doesn't work so well. And, with them scratching around they cover the poop up. So I can't find it well. When I tried to rake it ... it just gathers up sand and rocks... i can't see if I am collecting anything?? Maybe I am using the wrong kind of rake? I am worried that it will start to smell if I can't find or scoop out the poop... My husband has already commented that he doesnt' want to smell anything! Can I use the Sweet PDZ in the sand mix it in?? Anything else I can use to make sure that it doesn't start to smell? Any suggestions for foing on my poop hunt and getting it out? Thanks in advance?
