You could extend it further which would help with his behaviour, you do need to ideally put him on some lino though if he is weeing - mine are litter trained and are on lino in the conservatory with towels (cheap ones from Asda) interlinked/overlapped to allow them to move around without slipping and they sometimes dig them, dig their litter trays out, tip their hay baskets over, thats what rabbits do, he needs exercise and mental stimulation and he is clearly lacking it so he is finding his own ways to amuse himself, a digging box with some soil from the garden, a yellow pages to rip to shreds will keep him amused, have you thought about making him an outdoor rabbit ? The sounds, smells and fresh air outside might be more natural and calm him down if you really are losing patience with him, it's really not his fault remember that, he didn't ask to live with you, you got him - giving him more space will help along with other things to do to stimulate his brain.:wave:
