I'm new to FML so I hope I'm sending this to the right place to add it to the list... I just wanted to pass on to whoever was wondering about the Biodor stuff by Marshalls that it appears to work. I'm not entirely sure that it's the only explanation for the lack of odor. (When I adopted my newest carpet monkey her cage needed a good cleaning as did she, and with a good spray "bath" and cage cleaning most of the odor was taken care of) I've been using the biodor regularly in her water any smell that was there in the beginning is essentially nonexistant. I'd recommend it. Melissa M and Kiki [Posted in FML issue 3844]
