Hi, my book tells me (and it worked for me!) to place a number of boxes around the room and keep the rabbit confined to that room until he learns to use it. For the first week or two i placed just one litter box, with no joy. Henry just didnt get it! After reading the book, it said to place at least two boxes cos then they will groom themselves and sit in one box, then poo in the other. I placed another litter tray in the room and by the next day he had got the hang of it! It worked like a dream! Once you discover which box he likes, you can usually cut down until there is just the one box. Then you can allow him in another room. You may need to start the process of putting down a number of boxes again, however, henry didnt need this and now there is just one litter tray in the whole house and thats in his cage in the kitchen. Good luck!
