For those of you who have closed chambers, what is the best way you have found to clean/disinfect them? Looking for ideas as I currently have my little red foot in an old rabbit cage that I made a closed top for so I just take the top off to dump and clean the bottom, but I'm looking at moving him into a bigger closed chamber idea but am worried about not being able to clean/rinse it so easily. Any ideas would be appreciated! Thank you!
