Yes, just like cats, rabbits CAN be litterbox trained. You should plan on it taking a few weeks. Training your rabbit for a few minutes every day and staying consistent with your training techniques is important and will help your rabbit to learn what is being asked of him. There is a misconception that older rabbits cannot be trained, only very young bunnies. This is not true. In fact, some older rabbits are easier to train because they have a longer attention span.
Most cat litterboxes and litter materials are safe for rabbits to use. I have found that corn cob bedding works well, and because it is natural it is safe in case Twinkle decides to take a nibble of a few pieces of litter. Try to avoid using litters that are very dusty, as these are not good for bunnies' respiratory system.
2. Add a few droppings to the box so the rabbit's scent is in it. Your rabbit will also begin to get the idea his stuff belongs in the box, not the floor.
3. Place your rabbit in the box and praise him. If your rabbit does droppings outside the litterbox, scoop him up, firmly say no, and place him in the box.
4. Always praise your good rabbit.
5. If the rabbit's cage is large enough to have a litterbox inside (without the bunny feeling cramped) try training it in there first. Once the rabbit is trained, you can try him outside the cage.
This is my method of litter-training. I am happy to say that Twinkle now uses his box whenever he needs to, as opposed to going on my bedroom carpet. If you want more information on how to train rabbits, there are many good books that you can find in pet stores, or ask your pet's veterinarian for advice. Happy training!:)
