I've been throwing my bedding out and I hate doing since it seems like a waste. I live in "town" also but am thinking about an area I could do a small compost. Does anyone happen to know if aspen and rat/reptile feces is ok for grass? I've got some areas where I have a hard time starting grass and if I could "re-use" the soiled bedding that would be sweet but it probably needs to be broken down in compost first. With us trying to sell the house it probably isn't a good time to start a compost pile LOL.
