The litter box should be kept in a location that affords your cat some privacy, but is also conveniently located.
Type of Litter
You may need to experiment with several types before finding your cats preference.
Number of Litter Boxes
You should have at least as many litter boxes as you have cats. It is also recommended you place at least one litter box on each level of your house.
Cleaning the Box
Feces should be scooped out of the litter box daily. The box should be emptied, cleaned and re-filled weekly. Don’t use strong smelling chemicals or cleaning products when washing the litter box, as it may cause your cat to avoid it. Washing with soap and water should be sufficient.
Depth of Litter
Most cats won’t use litter more than about two inches deep.
Provide an acceptable, accessible litter box, using the suggestions above. Your cat will do the rest.
If Problems Develop
If your cat begins to eliminate in areas other than the litter box, your first call should always be to your veterinarian. Many medical conditions can cause a change in a cat’s litter box habits. If your veterinarian determines that your cat is healthy, the cause may be behavioral.
