Litter Box Priorities

According to Dr. Lisa Pierson “urinating and defecating outside of the litter box (…) is one of the most common reasons for a cat to be relinquished to a shelter”. Because this is so common, it’s important to understand what your cat wants in a litter box.

Cats want a box that is clean, large enough to turn around in, and in a location, they feel comfortable using.

Individual cats may also have preferences about the smell and texture of the litter they’re using, the ease of entering and exiting the box, and whether they will urinate and defecate in the same box or would rather use separate ones for each activity.

As cat owners, we want a box that is easy to scoop and keep clean. Odor elimination, visual aesthetics, durability, and shape/size are important factors when choosing a box, too.

Resolving inappropriate elimination may be as simple as changing the litter box to something that makes both of us happy!

How Large Should My Litter Box Be?

Average litter boxes at most stores are twenty (20) inches in length, and the average cat is approximately eighteen (18) inches from nose to hindquarters.

Ideally, the litter box should be one and a half times the length of your cat, and wide enough for them to turn around with ease.

In addition to offering additional space for your pet to move, larger boxes mean your cat has more room to avoid solid waste and clumps.

In a study from Nestle Purina, it was noted that odor and use by another cat were much less significant deterrents from using a box than the presence of solid waste.

Large, exotic cat breeds such as Savannahs, Bengals, and Maine Coons are experiencing a rise in popularity. At the same time, pet obesity has been on the rise over the past 25 years.

The Association for Pet Obesity Prevention states that overweight pets are at an increased risk for arthritis, affecting their mobility.

Whether your cat is overweight, an exotic breed, or just large, many traditional litter boxes may not provide the space your pet needs.
