Ok. I've never before actually seen anyone with cages that didn't have wire bottoms before. Until recently when i've seen y'all posting pics of breeder/show pens. My idea of a cage is one that has a wire bottom for the poop to fall down. For those of you who use a solid bottom with a layer of shavings, how much of a pain is it to change out shavings??? My thinking would be that it'd be an aggravation to constantly have to change out pine shavings.
