If you’re having a hard time persuading your cat to use the litter box, it just may be time to draw a line in the sand. Most cats prefer eliminating on a loose, grainy substance, which is why they quickly learn to use a litter box. But when their preferences include the laundry basket, the bed, or the Persian rug, you may find yourself with a difficult problem. By taking a closer look at your cat’s environment, you should be able to identify factors that have contributed to the problem, and make changes that encourage your cat to head for the litter box once again. The most common reasons why cats don’t use the litter box are an aversion to the box, such as dislike of a covered box, or dissatisfaction with the depth of the litter. Two other common reasons are a preference for a particular type of litter not provided in the box, or a preference for a particular location where there is no box.
