Poor upkeep of a litter box often leads to a cat's accidents. Cats dislike dirty litter boxes and may seek alternative spots, such as a corner of the carpet or clean laundry. A cat’s sense of smell is 14 times more sensitive than humans; hence, a box that seems clean to you might be unbearable for your cat. While automated litter boxes are becoming popular. However, they can be expensive for some pet owners, and many cats prefer standard boxes. Here's what you need to know to clean and maintain your cat’s litter box. Preparing to Clean Your Litter Box The rule of thumb is that a household should provide one litter box for each cat resident plus one extra. Any variance should be on the plus side. For example, seven boxes for four cats. If you have more than three litter boxes, you'll probably find yourself running out of logical places for them. A "litter station" with two or three boxes side-by-side will accommodate more than one cat at a time (as long as the cats tolerate it), and will also make scooping and cleanup a bit more convenient. The choice of litter box and cleaning products is personal, as a "one-size-fits-all" approach rarely works. The key is to let your cats guide you; if they are unhappy with the boxes or products, they will show it.

Ensure the box is large enough for your cat to move around comfortably, with no overhang. Position the box to maximize privacy, away from noisy appliances, and ensure there's an easy escape route. This is crucial if you have a cat who tends to bully other cats. Being trapped in his litter box will surely frighten the cat, and may lead him to avoid the box later.

Litter box liners are a definite advantage when using non-scooping litter because they contain the excess urine that seems to pool, which is the reason most non-scooping litter must be changed frequently.

Use three to four inches if your cat is a deep scratcher and tends to dig to the bottom. Start with two inches and adjust until you find the suitable depth for your cat. Clumping litter is advantageous because it doesn't require a pan liner, and most cats prefer unscented clumping varieties. After filling the litter box, smooth the surface to provide the cats with an even area for digging.

Separately, the poop gets coated with the litter so that it doesn't stick to the scoop. Scoop the litter box at least twice daily, or more frequently if necessary. Add fresh litter after scooping to replace what was removed.

With a product like the Litter Genie, scooping as well as disposal of litter is much easier. You just insert the roll of plastic bagging material inside the Genie, tie a knot at the end of it, secure it to a wheel, and turn the handle a half turn. Then open the top and drop in all the scoopings. Turn the handle again, and the waste is safely hidden at the bottom of the Litter Locker to keep all of the odors confined inside. On garbage day, just remove the bag and contents and discard it all in the garbage can.

Depending on the type of litter you use, this may be as often as every week or as long as every four or five weeks. Non-clumping litter requires more frequent emptying and washing because urine accumulates at the box's base, causing odors to become strong quickly. Empty the used litter into a sturdy plastic bag and tie it securely before discarding it in the trash. Note that although some environmentally friendly litters are flushable, the entire contents of a litter box should never be dumped into the toilet. Wash the box thoroughly with unscented dish soap and hot water. Rinse well and then dry with paper towels.
