Hi! I'm currently looking to change my rats bedding, as I currently have them on kiln dried aspen and have honestly grown uncomfortable with it for several reasons. Mostly, I'm just tired of it getting stuck everywhere! I was planning on moving my boys back on fleece, but the first time i tried it it was a disaster! I think my first mistake was not using actual liners and just clipping fleece onto the pan, so I know that much! Mostly my questions have to do with absorbency layers, but I'm welcome to any tips anyone has to offer! I don't quite know what an absorbency layer is, how to change one, IF you have to change one, etc. Any help is super appreciated! Thanks!
