Lore- Thanks for the information. I used to use fleece with absorbent liners underneath and found that it became smellier faster than normal bedding. I do wash their hammocks, etc. frequently and keep multiple sets to replace with while washing.

They are in wire cages now, and although I wipe down the bars, etc. with baby wipes frequently, the smell is pretty bad due to them peeing on the sides of the cage and the levels. I don't think the smell of poop is an issue, but rather the pee. They are on native earth 18 (harland teklad). I've heard the same things about the regal rat food.
