Got a cat? Then you probably have a litterbox. As more cat owners tune in to the importance of keeping cats indoors (for their safety and for environmental concerns), the litterbox issue is becoming more critical to the health and welfare of our felines.

Here’s the scoop:

The most common behavior problem reported in cats is ”house soiling.” It’s also the No. 1 reason cats are remanded to shelters.

There are three reasons cats tend to exhibit what we euphemistically call, ”elimination disorders:” Medical, such as a urinary tract infection; communication, as when your kitty’s stressed over something and announcing his presence; and litterbox issues.

Many times cats just don’t like their litterbox accommodations. Something may be ”off.” And any number of circumstances can make the bathroom box less appealing. Next thing you know, she’s not using it.

So take heed of the following:

• Cleanliness. Stay at least one step ahead of your cat’s litterbox cleanliness needs. If you’re just barely keeping up, the chances she’ll stray from her box increase exponentially if she’s stressed.

• Location. As in real estate, the location of the litterbox is critical. Moving it around can have disturbing side effects. But if he’s not using it all the time, you may need to try several locations to see what he likes best.

• Multiple cats. Here’s the key stat: 1.5 litterboxes for every two cats is considered the minimum. Sure, some can get away with less, but once you have three cats, you’re risking your cats’ comfort and your household’s aromatic integrity.

• Changes. Pick a product and litter depth your cats like and stick with them. The ones on sale look soooo tempting, but consider that your cats have to readjust significantly every time you make a change.

• Size. Yes, it’s been proven — bigger is better when it comes to litterboxes. Not only do cats feel more comfy and free in a sizable sand box, they also feel less threatened by invaders.

• Lids. Lids and close quarters can be especially disconcerting for cats who have to compete with other cats over territory. After all, how would you feel if you might be ambushed every time you left the bathroom?

• Litter. Studies show that cats prefer clumping litters. And odor-controlling litters can stretch the life of a slightly dirty box.
