So I think im adopting 3 boys in late spring/early summer, but I'm torn on the bedding choice. I'm getting a single or double critter nation cage and I think fleece is my best option for those cages. I do have a few questions for those of you who use fleece as bedding for your ratties. 1. How often do you clean it? 2. Does it stink? 3. Do you use anything under it?/Does it help?/Uhaul pads? 4. Any other tips for maintaining fleece for rats? Thanks!
