Litter boxes probably look more or less the same to us. We can purchase a self cleaning litter box, a regular box, a large box, smaller one etc.  but the type of litter box does matter to a cat. Jackie Neilson, a Veterinary Behaviorist in Portland, Oregon says that cats do prefer litter boxes with certain amenities. Jackies’ research shows that many cats prefer clay based clumping litter to other kinds. Cats also like their litter box to smell nice. Carbon is the top choice for odor control.  Most cats like their litter boxes roomy so they can dig and turn around comfortably. The bigger, the better but each cat has its preferences. You should find out the products that your cat likes best. If a cat likes its’ litter box it won’t find another one like a bed or a carpet to go on. So observe your cat and determine his likes and dislikes and you’ll never have to worry about any “accidents.”
