I have recently read about using borax (the cleaner) to kill the fleas by
sprinkling it on the floor, and after several hours, or days, vacuuming it
up thoroughly.  Is this too dangerous to try with ferrets since they are
self-cleaning?  What if I just leave them in their cage during the time the
borax is on the floor?
