You should clean the litterbox everyday,sometimes twice a day. I use wood pellets like for woodburning stoves.I scoop waste out in the morning and change entire litter every night.Also some kibble makes the poop smell worse. I have six ferrets and they never get a bath unless they get into something.I also change their bedding every week.They don't smell any worse than a dog does.normal animal smell. Hope this helps, Jodi and the brat pack. [Posted in FML issue 5220]
