Gee, I am glad you mentioned rabbits at the end of that description, I was thinking cat! (MY bias, haivng 7 of them, that is what comes to mind first for me.) And my concern was, how high will this "coffee table" BE?!

I don't know how much clearance you would need for a rabbit. Have you put in some measurements to see how high the top of the table would be? This may work better as an end table than as a coffee table, if you find the height won't work.

I've noticed that many of the cat litter containers are now being designed to do double duty, so you are right up there with the current styles. Some are being built "under" a plant pot, for a large house plant or a fake tree.

Don't know much about rabbits. If this were for a cat, you would more likely want the end where the ltiter box is placed to be solid wood - hidden from sight, giving the at privacy. The cat wouldn't use it out in the open.

Let us know when you have a model!
