If your cat is indoors, you have a litterbox. Your cat views it as a port-a-let, and
just like us when we are camping, they don’t like a smelly latrine. Be sure to clean
the litterbox daily and sanitize it weekly with hot soapy water. Clumping,
unscented litter is usually preferred by your feline friend. If your cat stops using
the litterbox, it may be dirty, or your cat may be trying to tell you that it is sick,
painful or stressed. Ask your veterinarian for help.
