Yes, you can train your pet rabbit to use a litter box. Rabbits are naturally clean animals and can be litter box trained similarly to cats. Provide a litter box filled with rabbit-safe litter and place it in a corner of your rabbit's enclosure where they tend to eliminate. Encourage your rabbit to use the litter box by placing some of their droppings in it, and reward them with a treat when they use it. Consistent positive reinforcement and patience are key to successfully litter training your pet rabbit.
