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

To train a pet 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 rabbit-safe litter and place some of their droppings in the box to encourage them to use it. Reward them with treats or praise when they use the litter box correctly. Consistency and patience are key in training your rabbit to use the litter box effectively.
