  Avoid clumping or dusty kitty litters, which can cause serious health problems if eaten. According to the House Rabbit Society, clumping litters clog the rabbit's digestive system and harm the respiratory tract. Autopsies have shown that rabbit intestines actually have been cut as the clay particles pass through.

  Avoid litter made from cedar, pine or other wood shavings. The shavings contain phenol and other volatile organic compounds which manufacturers claim produces a pleasant smell to mask odors, but the chemicals may actually kill your bunny. They can cause respiratory problems such as pneumonia when inhaled. In addition, the House Rabbit Society discovered that a significant number of rabbits that use the shavings as bedding die from liver damage.
