just aspen sucked for me, 3-4 days they smelled bad and needed to be cleaned

I read about all the things people complain about with pine pellets but then I had an idea

so I started putting a layer of pine pellets on the bottom of the tubs then aspen on top, the pellets absorb the smell way better, like I go a week to a week and a half without cleaning now. but the rodents still have their bedding, no ones getting sick, and everyones happy.

also doing it this way, cleaning the tubs has became way easier, the bedding just falls out now on most tubs instead of having to be scrapped out of every tub. another little added bonus

been doing this since I built my rat room, just after new years, because after putting them in an enclosed room, I needed to do something, even with ventilation, so I think I found a new system for me and had great results, feel free to try it out yourself.
