What are the best practices for training a rabbit to use a litter box effectively?

To train a rabbit to use a litter box effectively, start by placing the litter box in a corner of their enclosure where they tend to go to the bathroom. Use a litter that is safe for rabbits, such as paper-based or wood pellets. Encourage the rabbit to use the litter box by placing some of their droppings in it and rewarding them with treats when they use it. Consistency and patience are key, as it may take some time for the rabbit to learn. Clean the litter box regularly to maintain good hygiene and encourage continued use.
