For other litter material types, cleaning and removal of litter material should be done every 3-7 days. Remember, each cat is an individual, your cat may like more frequent cleaning of the litter box to maintain good usage patterns. The number of litter boxes needed depends on the number of cats, the size of the home, the temperament of the cat, and other pets in the home. Because there can be varied interactions between individuals, multiple boxes in multiple locations allow house-mates to avoid one another if they so choose. Even for only one cat, two boxes may be appropriate depending on the layout of the home and the individual preferences of the cat.
Some cats prefer one box for urine and one for stool.
Some physical limitation may prevent a cat from climbing stairs and so a box in the location the cat frequents is needed. In general, there should be at least one litter box per cat, and some behaviorists advise one more box than the number of cats in the house. Should the kitten begin to eliminate in locations other than its litter box, first review the steps above. You can determine the cat s preferred location by offering the preferred litter box with the preferred litter in two or more locations and determining which one, if any, the cat uses more frequently. If litter box problems then persist, additional guidance and perhaps a behavior consultation might be required.
