Does anyone have opinions on the litter maid litter box for use on ferrets? I am tempted to get it I know it will not be as effective for use with ferrets as it is for cats <no clumping litter, etc.> but my concerns are more that they will hear it, and go down to investigate it and possible get hurt from it. Does anyone have any opinions on this? or know anyone who has used it with ferrets? [Posted in FML issue 4725]
