Why Is My Cat Peeing and Pooping Everywhere?

There's a very specific kind of dread that comes with walking into a room and smelling cat pee or poop. And then there’s a whole other kind of dread that comes when you actually find it, whether it’s directly on the carpet, hiding behind the sofa or maybe suspiciously close to your favourite pair of shoes.

If you've found yourself frantically Googling “why is my cat peeing and pooping everywhere” at 11pm, you're definitely not alone, and despite what you might currently think, your cat isn’t doing it out of spite.

Because the thing is, cats almost never toilet outside the litter tray for revenge, no matter how pointed it seems. It's nearly always their way of telling you something's wrong, and it usually comes down to either a health issue that needs sorting, or something about their tray, their routine or their environment that's stressing them out.

So, before you start questioning your entire relationship with your cat, let's get into the real reasons this happens and what to do about each one.

Finding wee or poo somewhere it shouldn't be is never a nice moment, but the important thing to remember is that your cat isn't doing this to be naughty, no matter how it might feel at the time. When cats start toileting outside their tray, it's almost always because something isn't right, and your job as a responsible owner is to work out what that something is.

• Medical causes: Pain, urgency or a sudden increase in how much they need to wee can all make it harder for your cat to reach the tray in time, especially if there's an illness behind it.
• Stress and anxiety: Changes at home, tension with other cats or feeling unsafe in their space can be enough to trigger accidents, or spraying and soiling around the house.
• Litter tray problems: If a tray that isn't clean enough, filled with the wrong litter, or tucked away somewhere inconvenient, that can easily encourage your cat to go elsewhere instead.
• Territory marking: Spraying or soiling near doors and windows is often less about a toileting mistake and more about your cat marking what they see as their territory.

It's also worth paying attention to exactly when and where these accidents happen, because the pattern can tell you a lot. Wee on the carpet, duvet, sofa or in the bath tends to point to a different cause than urine sprayed onto a vertical surface near the bedroom door, so keeping track of this can help you (and your vet, if it comes to that) work out what you’re dealing with.

If your cat is needing to wee very often, straining, crying out, or only managing to pass a little or nothing at all, this is when to book an urgent vet visit within 24 hours rather than waiting to see if it settles down on its own. This matters even more for male cats, since a urethral obstruction can become life-threatening within just 24 to 48 hours.

And whatever you do, try not to punish or shout at your cat for accidents, however frustrating it feels in the moment. It won't help, and it'll usually just make your cat feel less secure which may even make the toileting issues worse.

Health issues are always the first thing to rule out when your cat starts behaving differently to normal including when they start weeing or pooing somewhere they shouldn't. Although it’s not always the case, it is possible that something isn’t right and they need some help from a vet.

• Urinary tract infections and cystitis: These both involve inflammation or infection in the bladder or urinary tract, and they're surprisingly common in cats. Look out for frequent, urgent little trips to the tray rather than one big accident, sometimes with straining or blood in the urine. And sometimes, the discomfort involved is often enough to make a cat start avoiding the tray altogether.
  
  
• Kidney disease and diabetes: Both of these can ramp up how much your cat needs to wee, so keep an eye out for noticeably bigger clumps in the tray, along with increased thirst or weight loss. Once the volume goes up this much, even a clean, well-placed tray can end up overwhelmed.
  
  
• Digestive problems: Tummy pain can make a cat reluctant to hang around in one spot long enough to finish their business, so diarrhoea, constipation or anal gland trouble can all end up leaving faeces somewhere they shouldn't be.
  
  
• Arthritis and mobility: A tray with high sides can be a big ask for a cat with sore joints, and it's worth knowing that plenty of cats start developing this kind of stiffness from around 10 years old, which can make a distant or awkwardly placed tray difficult to use.
  
  
• Cognitive decline: This affects older cats more than people often realise, with around 28% of cats aged 11 to 14, and roughly half of those aged 15 and over, showing signs of it. And some of these signs can include house soiling, disorientation and disrupted sleep. In these cases, it's less about misbehaving and more about your cat losing track of the toilet training they've always known.

If any of this sounds familiar, try to take a fresh urine sample and a stool sample along to your vet if you can manage it, and jot down when, where and how often the accidents are happening beforehand, since these little details can help get a diagnosis. The sooner you speak to your vet, the sooner you can rule out anything serious and get your cat back on track.

Knowing whether your cat is urinating or spraying makes a real difference to how you tackle the problem, because although the two can look similar at first, they're actually very different behaviours with different causes behind them.

Normal urination usually happens on a horizontal surface, with your cat squatting down to release a fairly large puddle of wee, often somewhere like the carpet, a duvet, the sofa or even the bath. Afterwards, you might notice them digging around or trying to cover it up, much like they would in their own tray.

Spraying looks and behaves totally differently because instead of squatting, your cat will often back up onto a vertical surface such as a door frame, wall or curtain, with their tail held upright and sometimes quivering. Then while their back paws do a small treading motion as they go, they'll leave behind a smaller, more concentrated jet of strong-smelling wee. They do this to leave a scent message for other cats, marking out territory that feels important to them or letting any passing cats know this space is already taken.

Both male and female cats can spray, and for pretty similar reasons, so this isn't just something male cats do. Unneutered cats often spray to attract a mate during breeding season, but plenty of neutered cats spray too, usually when something in their environment is stressing them out.

Once you've ruled out anything medical, there are plenty of everyday, entirely fixable reasons cats end up weeing or pooing indoors instead of in their tray.

• Dirty tray: Cats can be surprisingly particular about cleanliness, and many will simply refuse to use a tray that hasn't been scooped that day and choose a rug or a clean corner instead.
• Wrong litter: Sometimes, switching to a new litter they find too heavily scented or made up of coarse pellets that is uncomfortable under their paws can be enough for them to go elsewhere.
• Fear of outdoors: Things like stray or neighbourhood cats hanging around the cat flap, loud traffic, fireworks or bad weather can put your cat off going outside, leaving them to wee indoors instead.
• Household changes: A change in the home like a new baby, a new cat or pet, building work or visitors staying over can all chip away at how safe and settled your cat feels, and that unsettled feeling might show up as toilet accidents.
• Not enough trays: In multi-cat households especially, competition over a single tray can cause stress, but even with just one cat, relying on one tray in one spot is a bit of a gamble. If your cat ever feels trapped in a room or blocked from reaching their only tray, accidents are pretty much guaranteed to follow.

Even a healthy and perfectly happy cat will avoid a tray that doesn't suit them, so it's always worth starting here after you’ve ruled out anything medical. It’s surprising how picky our feline cats can be and how just mastering a few basics solves the problem quickly.

As a general rule, aim for one litter tray per cat plus one extra, and if you have more than one cat, try to spread the trays out around the house so nobody has to cross another cat's path just to reach one.

The tray you choose should be long enough for your cat to turn around comfortably, roughly one and a half times their body length. And for older, stiffer cats or kittens, a lower-sided tray tends to be much easier and more comfortable to climb in and out of.

Where you put the tray matters too, because cats feel pretty exposed while they're toileting. That’s why a calm and low-traffic spot with a clear escape route will help them feel secure enough to do their business.

It helps to experiment a little with tray styles too, since not every cat wants the same set-up. Some nervous cats feel safer in a hooded tray without a flap while others might prefer something open where they can keep an eye on their surroundings.

The litter itself makes more of a difference than most owners realise because it turns out cats have pretty strong opinions about it. Several studies have found cats typically prefer a fine, sand-like litter that's easy to dig and cover, laid to a depth of around 3 to 4cm rather than piled up thick and heavy. But of course, every cat is different so that won’t apply to all.

Keeping the litter unscented tends to be a safer bet too, since strongly perfumed or dusty options can sting sensitive eyes and noses, and if using the tray starts to feel unpleasant in that way, your cat may begin associating it with discomfort rather than relief. If you ever need to switch litter, doing it gradually over 7 to 10 days by mixing the old and new together gives your cat time to adjust, whereas an abrupt change could be one of the reasons your cat suddenly decides their tray is off limits.

And of course, you must stay on top of cleaning. Cats are proud creatures and won’t do their business somewhere that’s already dirty. You’ll want to change the litter entirely once a week and spot clean daily. When it comes to washing it, use a mild, cat-safe cleaner and let it dry completely before refilling. A good litter scoop makes the daily cleaning far less of a chore, and popping in a litter mat underneath the tray helps catch scatter.

Where you put the tray can matter just as much as the tray itself, since cats need to feel safe before they'll use one, and noise, activity or the wrong spot in the house can be enough to put them off. We suggest choosing a calm and private corner away from things like washing machines, dryers and anything else that might suddenly whir into life mid-squat.

It helps to keep them away from glass doors or windows too, since a cat who spots another cat outside while they're mid-toilet is unlikely to stick around and finish. It's also worth keeping the tray well away from food and water bowls, because cats naturally don't like toileting anywhere near where they eat.

If you live somewhere with more than one floor, it helps to have at least one tray on each level, so your cat never has to make a mad dash downstairs when they urgently need to go. And if you've noticed accidents happening right beside the tray rather than in it, it's worth trying a small move, sometimes shifting it just a metre or two into a more sheltered spot is all it takes to solve the problem.

Spraying indoors is almost always about stress and territory. It happens when a cat feels like their core territory, the space where they rest, eat and play, is under some kind of threat and leaving a scent mark there is their way of coping with that and feeling in control again.

Common triggers include a new cat turning up in the home or garden, strangers staying over, redecorating, new furniture and strong cleaning products. This is often why spraying shows up near doors, windows, bags or beds that smell strongly of a favourite person. Keeping that scent there helps your cat feel safe while everything else feels a bit unsettled.

Predictable routines help a lot, so try to keep feeding times and play sessions consistent. Giving your cat safe places to hide and rest matters too, since feeling secure is what solves this at the root. If spraying carries on even after ruling out medical causes and making changes at home, it's worth bringing in a qualified feline behaviourist for a bit of expert input.

A few changes around the house can help your cat feel safer which often makes a big dent in indoor toileting problems.

• Limit their space to start with: Keeping your cat to one or two quiet rooms stocked with food, water, litter trays, a bed, scratch posts and toys can help take the overwhelm out of a bigger home while you work through the problem.
  
  
• Add vertical space and hiding spots: Cat trees, shelves and a few hiding boxes give your cat somewhere to observe the room from a safe distance, and have somewhere calm to retreat to when they feel overwhelmed.
  
  
• Separate resources in multi-cat homes: Giving each cat their own bed, bowls and litter tray in different spots around the house cuts down on competition and the conflict that often comes with it.
  
  
• Build confidence through routine: Daily interactive play and predictable feeding times go a long way towards helping your cat feel like home is safe and things won't suddenly change on them.
  
  
• Consider pheromone diffusers or calming sprays: These can be a useful addition, but they work best alongside the environmental changes above rather than as a fix on their own.

None of us really want to admit our pets are getting older, but they do age, and like us, their bodies and brains start to change along the way, sometimes in ways that show up as accidents around the house. Arthritis, stiff joints or poor vision can make high-sided trays or covered boxes difficult to use, so a low-sided litter tray is often a worthwhile change for an older cat.

Conditions that become more common from around age 12, like kidney disease, hyperthyroidism and diabetes, can increase how much and how often a cat needs to wee, sometimes quite suddenly. Feline cognitive dysfunction can play a part too, causing disorientation at night, wandering, or toileting in unusual spots simply because they don’t remember where the tray is anymore.

A few small changes can help here, like adding several low-sided trays in easy-to-reach spots, popping night lights along corridors, and cleaning trays a bit more often for senior cats. But any sudden change in an older cat's toileting habits is worth a prompt vet check, since catching things early will make a difference to their quality of life.

Cats have an incredibly powerful sense of smell, so if they can still detect wee or poo on a surface, even faintly, it’s likely they’ll carry on treating it as a toilet.

• Blot, don't rub: On carpets, press fresh urine up with kitchen roll rather than rubbing at it, since rubbing just pushes moisture deeper into the fibres. On hard floors, soak up any puddles first before washing the area properly.
• Choose the right cleaner: Enzymatic and proper cat-safe cleaners work better than bleach or ammonia-based products which can sometimes draw cats back to the same spot. A 10% solution of biological washing powder mixed into warm water works well if you don't have a dedicated pet cleaner to hand.
• Clean it more than once: Giving the area at least two rounds of cleaning will help catch the odour molecules that linger long after a spot looks clean but still doesn’t smell quite right.
• Block off the spot temporarily: Closing the door, shifting furniture over the area, or placing a feeding station or bed there can help your cat unlearn the habit while they relearn to use their tray.
• Protect the high-risk spots: Using waterproof mattress covers and washable throws on beds and sofas can save you a lot of stress while you're working through the retraining period.

If you're feeling a bit overwhelmed by everything we've covered so far, here's a step-by-step plan you can work through over the next 2 to 4 weeks to get things back on track.

1. Book a vet check: Get this in within a few days, or the same day if there's any straining, blood, or repeated tiny wees. Once you've seen the vet, stick closely to whatever treatment they recommend.
2. Do a deep clean: Treat every previously soiled area with an enzymatic cleaner, and block off or repurpose those spots for a few weeks so your cat isn't tempted back to them.
3. Optimise the trays: Make sure you've got the right number of trays, in the right spots, filled with a comfortable litter at the right depth, and commit to scooping daily with a full change once a week.
4. Reduce stress at home: Give your cat a safe area with hiding spots and a few vertical perches to retreat to, keep an eye on how much access other cats have to the garden or cat flap, and make sure everything your cat needs is always within easy reach.
5. Keep a diary: Jot down the date, time, location and what was going on at home whenever an accident happens. This makes it much easier to spot patterns, and gives your vet or behaviourist something to work from if you need their help.

Persistent toileting problems isn’t a sign you've failed as a cat owner since plenty of cats need a bit of expert support to get back on track. If your cat is straining, crying out in the tray, passing blood, or not managing to pass any urine at all, treat this as an emergency and get to a vet straight away.

If accidents are still happening two to three weeks after treatment and any changes at home, it's worth going back to the vet to rule out anything that might have been missed the first time round. And if spraying or soiling continues from there, it's worth asking for a referral to a qualified feline behaviourist.

Whenever you do go in for an appointment, try to bring along detailed notes, photos of any soiled areas, and even videos of your cat's behaviour when they're weeing or spraying if you can get them. Having all of this to hand will help your vet or behaviourist reach an accurate diagnosis faster.

If you came into this wondering why is my cat peeing and pooping absolutely everywhere except the tray, hopefully you're feeling a lot less stressed and a lot more clued up by now. As we've covered, it's almost never about spite and almost always your cat's way of telling you something needs a bit of attention, whether that's a vet visit, a tweak to their litter tray set-up, or a little reassurance that their home is safe.

Getting to the bottom of it can take some detective work, and sometimes a bit of trial and error too, but with the right vet checks and a few changes around the house, most cats settle back into using their tray properly again.

And if you're in the thick of it right now, feeling like your home smells more like a litter tray than a living room, try to be patient with your cat, and with yourself. Here at WOOOF, we've got everything you need to make the process a little easier, from litter trays and enzymatic cleaners to calming aids and cosy hideaways, so you can help your cat feel secure and your home smelling like home again.
