Indoor cats poop on the floor due to medical issues (like arthritis, infections, digestive problems), litter box aversion (dirty box, wrong litter/box type, bad location, too small), stress/anxiety (changes in home, other pets), or territorial marking, with the behavior often signaling discomfort, dislike, or anxiety about using the box, requiring a vet visit to rule out health problems first.
Some options to change this behavior include seeing a veterinarian to rule out a medical issue, cleaning the litterbox and its area, purchasing a new litterbox or changing the type of litter used, changing the location of the litterbox, and even using obstacles to block certain locations where the cat may poop on the ...
When a cat starts pooping on the floor instead of the litter box it's a problem with one or more of these domains: medical, litter-box environment, stress/behavioral, or territory/marking. Diagnose by ruling out medical causes first, then adjust environment and behavior.
Using the litter box is instinctual for cats, so going outside the box is a signal to pay attention. Your cat may be stressed or have an underlying health issue causing this behavior.
Elimination problems can develop as a result of conflict between multiple cats in a home, as a result of a dislike for the litter-box type or the litter itself, as a result of a past medical condition, or as a result of the cat deciding she doesn't like the location or placement of the litter box.
Stress and anxiety are some of the most common causes of inappropriate elimination behaviors in cats. If your cat is pooping or peeing outside the litterbox and you know there's been a recent stress event in her life, this is probably the reason why.
You may also notice some subtle changes in your cats body language, including:
Never punish your cat for going to the toilet in the 'wrong' place as this will make the problem worse. It's always best to take your cat to the vet first if there's a sudden change in their behaviour, such as peeing and pooing where they shouldn't, in case there's a medical reason for the change.
Cat behavior red flags signal potential medical or emotional issues, including sudden changes in eating/drinking, litter box problems, excessive vocalization, increased hiding, aggression, lethargy, or changes in grooming (like overgrooming or stopping). Because cats hide illness well, any significant deviation from their normal routine, such as increased thirst, appetite changes, or unusual hiding, warrants an urgent vet visit to rule out serious underlying conditions like kidney disease, hyperthyroidism, diabetes, or pain.
The top "silent killers" in cats are Chronic Kidney Disease (CKD), often progressing until 75% kidney failure, and Hypertrophic Cardiomyopathy (HCM), a heart muscle disease, both often showing few symptoms until advanced stages, along with Hypertension (High Blood Pressure) and Hepatic Lipidosis (Fatty Liver), leading to sudden illness or organ failure if undetected. Early detection through regular vet check-ups, blood tests, and monitoring for subtle changes like increased thirst/urination, weight loss, or hiding is crucial for managing these common, often hidden, feline diseases, says this article.
A stressed cat may exhibit changes in their urination or defecation habits. Loose stool or diarrhea can be a symptom of stress or a variety of illnesses. Occasionally, cats will urinate or defecate outside the litter box or in inappropriate locations if they are stressed, painful, or sick.
One of the primary reasons your cat might be pooping on the floor is due to medical issues. Conditions like constipation, diarrhea, or inflammatory bowel disease can cause your cat to associate the litter box with discomfort or pain. When this happens, they might avoid using it altogether.
Cat dislike citrus scents, so any combination of orange, lemon, lime, and/or tangerine peels that totals a cup (96 g) will work for the repellent.
Some medical issues that could lead to house soiling include: Digestive problems. Constipation, diarrhea, inflammatory bowel disease, or other digestive issues that can cause a cat to feel a sense of urgency or pain when pooping can lead to the cat avoiding the litter box.
Soil or fine play sand is perfect as it is easy for your cat to dig. You could place a litter tray containing your chosen material outdoors. Or you could dig a toilet for them, the same size as a standard litter tray or bigger, and fill it with the material.
Your cat may have litter box trouble for any number of reasons, including medical problems, an aversion to the litter box, or a preference for urinating or defecating in places outside the box.
New Cat? Set Realistic Expectations! You can expect that it will take your cat some time to get used to the new routines and environment. The 'Rule of Three' means that you can gauge the time it might take for your cat to fully acclimate to his home in threes: three days, three weeks, and three months.
You can tell if a cat is sad by noticing changes in their behavior, like loss of appetite, excessive sleeping or hiding, poor grooming, increased vocalization (especially mournful cries), changes in litter box habits (urinating outside the box), or showing uncharacteristic aggression or clinginess, as these often signal unhappiness, stress, or illness. Always consult a vet, as these signs can also point to medical issues.
Most Common Cat Behavioral Issues
In case you were wondering, cats do not poop out of spite or for revenge. This behavior likely means your cat is trying to tell you something.
Cats hate strong, pungent, or overly sharp smells, with citrus (lemon, orange), vinegar, strong spices (pepper, garlic), certain herbs (lavender, eucalyptus, rosemary), and harsh cleaners (ammonia) topping the list due to their overwhelming intensity and potential toxicity. These scents irritate their sensitive noses, often causing them to recoil or avoid areas where they are present, making them useful for humane deterrents.
Some cats don't like the feel or smell of wood pellets, or clay, or sand, or corn, or clumping, or non-clumping… you catch our drift. It might be as simple as changing to a different type of litter to stop your cat from pooping on the carpet.
If your cat has anxiety, you may notice pacing or restlessness, hiding, decreased appetite, vocalization, hypervigilance, trembling, salivation, and excessive grooming.
Symptoms of stress
Urination or defecation (pooping) outside the litter box falls into two categories: toileting and marking. Toileting often indicates an underlying medical condition or incomplete litter box training. Marking, or middening, occurs when a cat uses feces instead of urine to make a statement or communicate.
