Does anyone have any suggestions as to a nontoxic cleaner for my cement floors under rabbit cages? I can't stand using bleach because of my asthma and I worry about the rabbits as well. I have wire cages with trays but the rabbits sometime miss and the floor still gets wet/messy. I sprinkle wood shavings to absorb the moisture but I still need to clean/disinfect the floors once a week when I'm cleaning out the cages. What do you folks use?
