Yep, I get the poo issue, too. However, I found a magic tool that, when taken out to the cages each day, magically cleans away the molting fur/poo mixture that seems to appear each morning in certain cages.....are you ready?.....ok, here goes....it's a........putty knife! You know, those scrapy doo-hickys that you use to either spread dry wall mud (quick note: NEVER EVER try to dry wall a room with your spouse-it can lead to murder/divorce/mean things said, etc.) or whack your husband in the back of the head with?-see parenthetic note earlier. Anyhoo, it scrapes up that icky spot lickety split and makes it easy to kind of "spatula" out of the cage. Keeps things much cleaner.
