    6. Issue: Your cat pees inside the box, but poops outside of it.

    Solution: As with many of the other issues, this could be your cat's way of communicating health problems. Check your cat's litter for diarrhea. Also see if your cat appears constipated while using the box. With this information, take your feline to the vet and see if this is the outward expression of an internal problem. If your cat is older, it could be pooping outside of the box because arthritis is making it too painful to go inside. Try adjusting the box and litter type so it is more comfortable. Finally, your cat could just be picky or expressing emotional issues. Be patient, and try adjusting its surroundings until you see positive results. (The Happy Litter Box)
