Litter Box Accidents
How often do you clean out the box? Is the box in a high traffic area? Have you added additional cats without adding additional boxes? Have you changed brands of litter? All of these might cause litter box accidents. If there have been no household changes to trigger this behavior, a trip to the vet is in order. Your cat may have feline lower urinary tract disease (cystitis) and needs treatment immediately - do not delay - your cat could die if he or she has this disease and is not treated.
