Litter Box Training

One of the big advantages of owning a cat is that almost all cats come litter box trained. By nature, they will urinate and defecate in a soil-like substance if it is provided.

The Litter Box

The number one behavorial problem of cats is urinating out of the litter box (inappropriate urination). There are several things that cause this frustrating problem, but some of those are related to the litter box. The following comments are included to prevent problems later because cats are particular about their litter boxes, the litter, and the location.

Choose a litter box that is large enough for your cat to fit in comfortably. It needs to be able to turn around freely. An 18 X 14 inch box with 4 inch sides is appropriate for most adult cats. Kittens may need a box with shorter sides so they can get in and out easily.

We do not recommend a box with a top (hood). Although hooded litter boxes are more private and better contain the litter, they also trap odors inside. Because cats are so fastidious, these odors often cause them to seek other places to urinate. Many cats exhibiting inappropriate urination will return to their litter boxes when the lid is removed.

Litter Box Location

The location of the litter box is important. It should be on an easily cleaned surface, as some cats don't always aim well. Litter is also scratched out or tracked out of the litter box frequently. It is very important that the litter box be placed in a quite, non-threatening location. Cats need their privacy and will avoid a litter box that is in a high traffic area or a location accessible to dogs.

Types of Kitty Litter

There are three types of litter: clay, clumpable, and organic.

Clay litter absorbs 75-100% of its weight in moisture. This is good but not adequate to keep urine from being absorbed throughout a widespread area of litter. Solid matter and wet litter should be removed 1-2 times per day, but the entire litter box should be changed weekly. Clay litter is also quite dusty. Cats with allergies can have increased problems when breathing the litter dust.

Clumping litter is also called scoopable litter. It absorbs urine and swells to about 15 times its original volume. Therefore, you need only to remove the litter clumps; you do not need to change the entire contents of the litter box. It tends to control urine and stool odors better than clay litter.

Organic litters are made of alfalfa, newspaper, peanut hulls, corn cobs, or recycled, biodegradable materials. They appeal to many cats, but they are also not received well by others.

Some litters contain scented or odor-controlling additives. Some cats tolerate them, but others find them objectionable. To minimize the chances of inappropriate urination, it is better to avoid scented litters.

Cleaning the Litter Box

Fecal matter and wet litter need to be removed once daily for each cat that uses the litter box. Even with clumping litter, a monthly scrubbing of the litter box removes odors that may collect in the box itself. Use warm, soapy water and avoid scented disinfectants.
