i'm not an indoor advocate but if it is that what you have, here are something to consider:
_watchout for them rabbit pellets (got too much bad rep lately!) or hay they need to be replace on a regular basis.
_orchid bark, cypress mulch can retain high humidity which might be best for a WARM hide box.
_top soil is ok in general for walking/basking, you can also try eucalyptus mulch for this same purpose.
_newspaper is quite good for their diner table, what you can do is build a "food" tray to house the exact size of your newspaper (half page/full page/quarter page...your choice of space in ratio to the enclosure), then make another frame to fit within that tray to sort of "clamp" a small stack of daily news which serve as "table napkins" so that their aftermeal clean up should be a cinc...
those are just the few pointers, the idea is to be creative, to experiment a little and let your bambino show you what's his prefs are ...spoiled brat you may say
