My girlfriend and I spot clean and change water everyday. I'll start making sure the bottoms of the dishes are completely dry before putting them back in and I'll be more careful sliding the tubs back into the racks. If I were to switch to paper towels, how often do you swap out the towels and do you clean every time you swap out the towels? Can you spray a tub with paper towel bedding to help with humidity? Etc. And a question about Cypress.. how does it smell? I know a weird question but, my girlfriend is very sensitive with smells. We tried buying a different type of Aspen before but it had a strong smell and she couldn't take it, we have to buy the Aspen from Petco that's like $21 per bag and doesn't have much of an odor to it.
