When it comes to the litterbox, will your cat tell you what she really, really wants?

Okay, first of all, leave it to youtube. Look for cats singing “Wannabe” by the Spice Girls and you’ll find this bizarre video:

Now, time to get serious. I help a lot of people who are experiencing behavior problems with their cats – and a lot of those cases have to do with litterbox avoidance. There are several reasons that cats may stop using the litterbox – including medical problems, an undesirable litterbox location, substrate dislike, or even stress. Solving the problem often requires several different approaches, including modifications to the litterbox and the owner’s behavior. Sometimes the problems are obvious – like a dirty litterbox, or a box that is hard to access. Other times the cause is more subtle.

But one important question – can you assume your cat likes the litterbox just because she uses it consistently?

Think of it this way: if your only bathroom option was an outhouse, would you use it?

Hey, when you gotta go, you gotta go. My guess is yes.

But if you had your druthers, maybe you’d rather pee here.

If you didn’t have a choice, I might assume you LOVE using the outhouse, because I’d see you doing your biz there. But having a choice could significantly change your behavior! You might find the same is true of your cat.

I’ll speak from my own experience. My dearly departed kitty, Jesus (his name is another story), had asthma, so I used pellet litter to prevent dust-induced asthma flare-ups. He always used his litterbox, and I assumed he was just fine with our litter arrangement. THEN I got new cats, who got clumping, sandy litter in their boxes. Once he realized what *they* were getting, he wanted to try it out too. And then he stopped using his own litterboxes so that he could use what he REALLY liked, the sandy stuff. I ended up switching all the cats to the same litter. All those years that I thought he was “fine” with the pellets he was probably bumming out on those hard pebbles under his delicate paws.

So what do cats want in a litterbox?

Keep it clean, keep it simple.

No need for a robo-box. Just a basic box, four walls and some unscented kitty litter. Studies show that cats tend to prefer clumping and sandy litters over chunkier litters (1), and if we think of their natural history, it makes sense. Cats are descended from wildcats who used desert sand to eliminate in. Keep it real, feline style. And don’t forget to scoop at least once a day!

Size matters.

One study looking at whether cats preferred covered or uncovered boxes (2) found that some cats liked covered boxes, some cats preferred uncovered boxes, and some cats were happy to use both. The key to this study (in my opinion) was that both types of boxes were jumbo! They used modified storage bins instead of traditional litterboxes, which are way too small for most adult cats. Most covered boxes that you can buy commercially are NOT big enough, as the recommended size of the litterbox is one and a half times the body length of your cat. And commercially available covered litterboxes like the Booda Dome take up a ridiculous amount of space for the actual amount of litterbox you get out of them.

I LOVE the storage bin as litterbox, and my cats seem to, too. You can cut an entryway at whatever height works for your cat. They prevent litter scatter, and they are also good for cats who don’t squat when they urinate and tend to pee over the edge of the box.

Ease of access.

This is especially important for older cats and kittens, but really it may matter to any cat. Humans want to have a bathroom on every floor of their homes, why shouldn’t cats? Would you want to trek out into your chilly garage to go to the bathroom? I didn’t think so. Furthermore, some covered boxes (such as top-loaders, boxes with flap-doors, and litterboxes that are hidden in furniture) can be difficult to get into, much less turn around to find just the right position to poo in.

So if they're using it anyway, why does it matter?

Not to stress you out, but it might be stressing your cat out.  Just like you might use that outhouse because you had no other reasonable option --- your litterbox might be "close enough" to bring out your cats instinctual behavior (let's face it, one thing that makes cats so amazing is that they need NO TRAINING to use a litterbox --- put down a box of kitty litter and they know what to do), but not quite close enough to make them feel completely-kitty-comfortable doing so. Cats that do not enjoy the litterbox may be less willing to use it, and may hold their urine, which increases the concentration ("specific gravity") of their urine and may lead to bladder stones or crystals. Urine retention is one possible cause of Feline Lower Urinary Tract Disease (FLUTD).

So give them a choice and let them vote!

The reality is that many cats may not care. I’ve seen situations where five cats shared one box (not recommended, but…) without incident, I've met huge cats who would faithfully use a teeny tiny litterbox, or have no problems navigating through an obstacle course of cat flaps and stored junk in a garage to get to their litterbox that was in the most remote corner of the house. But once you’ve got a litterbox problem, you’ve got to solve it, and it’s much easier to just prevent a problem in the first place.

So, if you want to be sure, try offering your cat a few choices of litterboxes (a cafeteria, so to speak) to see what she really, really wants. If she loves her original box, she'll come back. If she doesn't, it was never meant to be...
