A. Have your pet seen by your vet to rule out medical causes. To rule out UTI, have your vet collect a sterile sample for urinalysis and culture. Since you have multiple cats, the general rule of thumb is to have a litterbox for each cat in the house plus an additional litterbox. Try different types and brands of litter. Your cat may prefer one to another. Try litterbox attractants. Search www.pet360.com for options. If your cat is stressed or feeling anxiety, try to determine and reduce or eliminate the offending stimulus. If that isn't possible, calming pheromone collars or sprays may be effective. Use an enzymatic cleaner such as Nature's Miracle to clean up any surfaces.
