I'm a bit confused when it comes to bedding.. what does it actually mean? Putting hay on it? Or some towel? Bedding is for sleeping or izzit for toilet usage?... And do I need to change the hay everyday ( as in removing all of them and replacing them with new one )? Or I just need to put more hay? What material should I put for their toilets? ( assuming I am going to toilet-train them as in putting their poos on the toilets ) thankz
