I have laminate flooring on the shelves and fleece on the drop pan (R-695). I clean their tails every few weeks by soaking them in the tub and using a toothbrush, but it doesn't seem to get all the dead scales off...it gets some of them off and gets the dirt off, but they still have dead raised scales. Maybe I should be cleaning their tails more often? Or at least, what daily, until all the dead scales are gone?
Like I said, my older ones are ok...I don't know why the younger ones tails get SO terrible (they're in the same cage).
