Hey I was wondering how often everyone cleans their tubs/enclosures. I use aspen bedding, and spot clean every day. Waste is never left in the enclosure for more then a day ever. As soon as I come home everyday I remove any kind of nastiness, so I keep them pretty clean. When she pees I usually remove the saturate aspen as well. But when should I change the aspen? Its prolly been in there since october. No smells or anything like that either. Whats usually a good rule of thumb for cleaning, and replacing aspen??
