Ok so i started with a basic cube but the carboard on the base was getting horrible to clean up so I upgraded and made a split level house for Bunny

I need to put a better floor board on this level but did got get that far today so cardboard will have to do,

I am hoping to add another level later down the track.

One thing, I put him on the top level and he has stayed there, should I give him a ramp?  All of these that I have seen no one seems to have ramps but if he needs one (as he is small) then I will add one in, any suggestions what to make it out of?

 Many people recommend coroplast for the bottoms, but it's a bit hard to find. I found a seller on Ebay that makes pre-cut squares that fit with NIC cubes.

Also, they have this new ramp you can get. I would check it out, and go to their Ebay store for the coroplast. Many colors.

Yes, that's what I was thinking to Moobunnay, a cardboard hidey box that he can jump on top of also. Otherwise, if you have another grid or two, join together with cable ties, attach two lengths of dowel underneath them, then cover the top of the grids with carpet or sea grass mats. (also can be cable tied onto the grids.)  If you find a box or ramp take up too much floor space, maybe put a intermediate "step shelf" onto one of the sides perpedicular to where the large shelf is.   The coroplast mentioned can be found at Bunnings in Australia- it's called Flute board.
