My bunny, Baba, is not neutered. It may be a little of both causes because that same day he pooped and peed on the bed for the first time. I have several rabbits and they come on the bed at different times to run around. I cover the bed with different cloths, but the odors may get through, so it may suggest that he is marking his territory. He was rubbing his side against my ankles when he was circlling. He is also a benign cuddle bunny who loves nothing more than to be hugged and petted for as long as I am able to do this. What is your final opinion on this and how can I stop him from pooping and peeing on the bed in the future. This last question is most important as I hate to ban him from the bed. He is a very spoiled bun.
