Prevention is easier than the cure is never a truer statement then when considering litter box etiquette.
There are many types of litter to choose from. Clumping litter is convenient because it is easy to scoop. Scented litter may diminish offensive smells for us but may be objectionable to your cat. Cats have strong preferences for the type of litter they’ve grown accustomed to. They may display their displeasure about your new choice of litter by doing their business elsewhere.
Cats prefer a box located in a quiet but not “cornered” location because they want to see another cat’s approach. Most prefer a large box, with low sides and a moderate level of litter. Cats usually don’t like a covered box which can concentrate odor. They really like a clean box, so scoop it daily and wash box with warm water and completely replace litter weekly. Avoid placing it near food, water, sleeping spots, or room deodorizers. In fact, a good way to discourage a cat from soiling in specific areas is to place food bowls, toys, and beds there.
Elderly cats may become reluctant to climb stairs to use a litter box so keep one, with low sides, on every floor. If fact, you should always have one more litter box than the number of cats to reduce conflicts.
Follow these suggestions so your kitty’s business doesn’t become your business.
