I don't know... Mr. cookie is allowed on all the furniture, but he also doesn't have any yucky habits...
The only thing I could think of was tin foil? My dad used to do that for his cats... To keep them from jump into the baby's crib, the leather chairs etc... I don't know how well that would work with a rabbit tho, cuz I imagine they would try and chew it?
I'm sure someone else will have a better suggestion for you! Good luck!
