Hi - your rabbit will train itself if you let it - provide a litter tray and acquaint your pet with it, he'll be as keen as you are to keep his home nice. They like to always go in the same place so once you know their preference you can act accordingly. We used to have a house rabbit and a house guinea-pig years ago and they were very clean and odourless. The Fuller's Earth based litters are the best - Tesco do it and it lasts for ages. Bye now
