The right litter makes a litter-trained rabbit’s tray easy to clean and keeps odours down, while being safe if the rabbit nibbles it. Paper, wood and straw pellets all work, each with trade-offs in absorbency, dust and cost. Avoid clumping cat litters, which are dangerous to rabbits. We compared rabbit litters on absorbency, odour control and safety, so cleaning is easy and your rabbit stays safe.
