Teach your cat to use the toilet in three easy steps. The line for the toilet just got a little longer thanks to the LITTER KWITTER Cat Toilet Training System. LITTER KWITTER is an award-winning system designed to rid your home of the smelly and unhygienic litter box by training your cat to use the regular human toilet in eight weeks or less. The system includes a white toilet seat cover and three colored rings. Start by placing the seat cover–including all three rings filled with litter–on the ground next to the toilet, then gradually move them onto the toilet. Once positioned on the toilet, you can begin removing the inner rings and reducing the amount of litter to lead him through the three stages of behavior modification–balancing on the toilet, aiming into the bowl, and finally, relieving himself without the need for litter. By gradually reducing the amount of litter and increasing the size of the opening over time, your cat can become one of the more than one million cats that have learned to use the toilet since the product was launched in 2005.
