Hello, My mother currently has five rabbits (not sure of the specific breed or anything) which live in her basement. We're looking into the possibility of building them a hutch, as for right now they're just confined by small fences which take up a lot of horizontal space. The space is relatively flexible, but the goal would be to create a reasonably large and multilevel hutch for them to live in. Any help with this project would be appreciated, but more specifically I'm wondering about the possibility of giving them a bottom area filled with dirt for them to burrow in (basically, to build a box of dirt and then place the hutch on top of it so they have a dirt floor). Is this a feasible idea? Would there be issues with cleaning their waste (and if so, how often would the soil need to be changed?)? Would it be worth the effort? All-in-all, just wondering if you guys think this is a worthwhile idea or if we should just stick to a more standard hutch.
