What to Do When Your Cat Refuses to Use the Litter Box
A cat behaviourist explains why they’re so particular about where they pop a squat
Generally, cats can teach dogs a thing or two about doing their business. If you let them, a dog will walk right past a tree to lift their leg on your neighbour’s car rims, then strategically poo at the bottom of another one’s garden path. Besides the fact that cats can be trained to use a human toilet (haven’t you seen the TikToksopens in a new tab?), these diminutive geniuses will politely regulate their BMs to a litter box – that is, until they won’t.
It turns out there’s a lot more going on in a litter box than numbers one and two. Come on, think of your own five-step nightly skincare routine – cats have their particular habits, too. While they’re not exactly trying the latest anti-ageing serum in there, cats do get up to other activities in their litter boxes, including guarding and playing in it. But avoiding the litter boxopens in a new tab altogether? Not cool, kitty. We caught up with Dr Niwako Ogata, director of the Purdue Animal Behavior Clinic at Purdue University, to get the scoop (pun intended) on why this happens and what you can do about it.

Change is bad
OK, change is good, but don’t expect your cat to be down with it. Many pet parents believe their animals spite-wee and revenge-poo to show their disapproval for something, like losing sleeping-in-bed privilegesopens in a new tab thanks to a new partner. The argument can be very convincing, especially when they seek out your pillow when there are umpteen less gross, but equally rude, locations to stage a protest. But Dr Ogata says anxiety is more likely to blame when a cat won’t use the litter box and adds that cats are notoriously fussy creatures who may react to the slightest change in their environment – even just a new type of litter.
Location, location, location
The grass is always greener… or the rug softer. Maybe it’s the downy material or the absorbency or how it’s just so nice to kneadopens in a new tab. The jury’s out as to why many cats prefer rugs to litter boxes, but if yours is guilty, either limit their access to the room with the rug in question or spray it with a sour-smelling deterrent. Another favourite place to ‘go’ – which admittedly makes more sense – is in a potted plant, where they can bury their business. If your cat has abandoned the litter box (or never attempted to use it in the first place) consider where it’s located. Dr Ogata recommends a quiet, private area that’s easily accessible and far from their food and water bowls – but not so far that it‘s next to the loud, clanking washing machine.
Size matters
Most cats prefer larger litter boxes and litter made from small, clay granules (as opposed to silica or wood pellets). Some may care not for privacy and avoid litter boxes with lids. Dr Ogata also says that you should pass on litter boxes disguised as household objects like side tables and ceramic pots. They are purely aesthetic – something your cat will not appreciate (and then will proceed to poo under the bed). She adds that “an open shape is better”.
Comfort zone
“If there is a sudden change in litter box habits, make an appointment with the vet to rule out medical causes,” says Dr Ogata. Cats can get UTIsopens in a new tab, too, which causes pain when they pass urine. They could assume that the litter box has something to do with it and associate pain with it. Climbing into and out of a litter box could also present a challenge to an ageing, arthritic cat.
Private and guest baths
If you have multiple cats, it follows that you have multiple litter boxes – you should, anyway. Dr Ogata suggests one litter box per cat, plus one extra. So, two cats equal three litter boxes? That’s right. It’s not that your cats are divas; it’s just in their nature to be territorial. “In multi-cat households, cats can be bullies and the aggressor can block access to the litter box,” she explains. Observe your kitties and place litter boxes where each one likes to spend time – the further apart, the better.
Clean up your act
Your cat feels about a dirty litter box the way you do about a crappy pub’s toilet facilities. The sight or scent of poo will send them running in the opposite direction. “The most important thing to a cat is the cleanliness and smell of a litter box,” says Dr Ogata. “A spot that is wet, dirty or smelly will deter them from going back.” And if they’re well trained, they will hold it, which can cause bladder and kidney issues. If you’ve been eyeing automatic litter boxesopens in a new tab, you may need to think twice. The unexpected motor noise or motion can startle sensitive cats. Get into the habit of scooping out the litter box at least once a day; set an alarm on your phone as a reminder. Your cat will thank you by going where they’re supposed to.
