My fiancé and I got a mini lop male rabbit named Oreo. He's around 4 months old. And we let him roam the house every now and then. Once Oreo discovered he could hop onto our bed he pees on it. We have to keep a close eye on him when we let him out now because the moment we look away for a minute he will hop onto the bed and pee on the bed. I need help and advice! Why is he doing it and how can I put a stop to this behavior?
