That’s a very nice set-up Beka!
I too would recommend something other than the rabbit cages sold in the pet store and definately no hutches either. The cages sold in pet stores are too small and the hutches are too as well as the wire bottom being very bad for your rabbit as they have a multitude of problems like sore hocks, catching nails and tearing them out. A very lage wire dog crate works well too, NIC condos are very nice, but like Beka mentioned do take some time to construct and you will need to use certain tools like a saw and wire cutters and will need zip ties (cable ties), NIC panels, 1 X 2″ lumber to support the shelves, lining the shelves, cutting it to fit and what is really important is constructing it properly so that it doesn’t bow or have some structural problem and it can take quite a bit of trial and error. I’ve made several, even one for a Chinchilla and I’ve got it down to a science now and find that I improve with each one and cut back the time I take to a couple of hours when I have all the supplies at hand – that includes making a cart for it.
So, if you have a lot of room x-pens are really nice. If you have a smaller space and don’t want to or can’t do a NIC condo, a very large wire dog crate works nice, and you can put a shelf in there with a towel lining the bottom of the cage and of course offer free-roaming time as they really should not be kept confined in a smaller home 24/7.
