Okay, so I had to leave my Herp Kittehs in my apartment while I had some medical procedures done this past month. My sister was coming in and feeding them and sorta cleaning out of the litter box. Of course the first thing I did when I came home was hose out the box and mop the bathroom floor but this place still absolutely reeks! I can't find where it's coming from. I'm about to start brush scrubbing my entire carpet in hopes that will help. What works best on getting rid of that horrid smell?
