Cleaning a litter box is very painful for many people around the world. I think you should be aware of two products that make the experience more pleasant. These two cat products are the Littermaid and the litter robot.
The Litter maid uses a rake to sift through the litter and transfer the waste into a separate bag. The motor and rake which is the core of the system unfortunately breaks down easily. The main cause seems to be larger chunks from the litter gets caught under the rake and jams it.
If you do not want to take a chance with the Litter mad, then the Litter Robot is for you. It uses a sifting technique to dispose of the cat droppings and urine soaked litter. This has no rake which reduces the chance of breakdown. Most people do much better with the rotating sifting technique litter boxes rather than with the old school rake style.
I like the Littermaid because of how easy it makes waste removal. It puts the waste in the bag for you automatically. The catch is that these are special bags and you would need to buy them again. The Litter Robot makes you have to remove the tray and transfer the waste to another bag. Each of these systems work well but the Littermaid is more advantageous.
The prices can be a deterrent to many people. The Litter Robot costs more than three hundred dollars and the Litter maid is less expensive in most pet shops. Just keep in the back of your head that the Litter Robot does not need special waste bags that need replacement.
In any account, I would say that both of these systems are worth every penny. Not having the smell and hassle of cleaning traditional litter boxes makes it all justifiable.
