Hi! We have two girls in a 2x4 and recently switched from Carefresh to fleece. I love the easy clean-up and sweep/vacuum poop 2-3 times/day. BUT our cage stinks just a few hours after I put fresh bedding in it. I can't figure it out. Our fleece wicks great and stays dry. For under-layers, I've tried an absorbent mattress pad and puppy pads. The coroplast isn't wet when I take everything out for washing, and both layers have seemed to absorb the urine fine, but the whole room (a sizable bedroom) stinks! I put in new bedding yesterday afternoon and by last night it was already stinky and I felt like I needed to wash it again. Should I switch to towels or Uhaul pads? Or maybe fleece isn't for us? I know there will be some smell, but this is overpowering. Any thoughts are appreciated! Thanks!
