Roscoe (neutered) and Lily (unneutered and elderly) have been bonded for a few weeks now. Roscoe has always been fantastic with his litter box (few droppings here and there, but always pees in litter box). When I did some research, many people suggested that an un-trained bunny can learn from a trained bunny. This has not been the case.
I moved their pen from the floor to the top of the desk with two giant litter pans (under the desk boxes), because the floor could not be kept clean. When I had Roscoe on the floor before they bonded, the pen was always in good shape and he never had the yellowing feet. The same thing happened on the desk. Despite my frequent desk/cage washing, they both have black and yellow feet from her marking and running through it.
I made them a new NIC cage because the desk got to be too awkward to clean often. This one seems to be great– but now she’s still peeing on the shelves.
Do I remove her and try to litter train her separately? Or do I work hard at wiping down the shelves whenever I see pee? I washed their feet gently last night because I was worried that the effects would be long lasting. I feel terrible!
