Very nice When I am eventually able to build a C&C cage, I plan to build mine with the same dimensions
The only issue you might have here is with the ramps, some rabbits have trouble with them (mostly going down) and since they are quite steep your new bun might have trouble. If you notice that your bunny isn't using the upper level (or is stuck on the upper level), then it could be worth extending the top shelf to three grids long and making it a jump up/down, most rabbits do well with that. But it's not something you'll know until you get your bunny Very exciting, hope we get to see pics after you get her
