# Senior Cat Peeing in Sleep or Pooping on the Bed: What It Means A senior cat peeing in sleep is not simply part of getting old. It usually means something has changed in your cat's bladder control, and the most common reasons are medical: a urinary tract infection, kidney disease, arthritis that makes it hard to reach the box, or nerve and muscle problems that weaken the urinary sphincter. The same is true for a senior cat pooping on the bed. Loss of control at rest deserves a veterinary visit, often soon. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - A cat who leaks urine while sleeping has lost voluntary control of urination, which is called incontinence. This is different from a cat who deliberately pees outside the box. - Common causes include urinary tract infections, kidney disease, arthritis, cognitive changes, and nerve or sphincter problems. - Any senior cat with new incontinence needs a veterinary exam and a urine test. A urine sample is often the single most useful test. - Do not withhold water to reduce accidents. Cats with kidney disease need steady hydration, and restricting water can make things worse. - If your cat is straining to pee, crying, or producing no urine, treat it as an emergency and call a veterinarian right away. ## What Incontinence in a Senior Cat Looks Like Incontinence means urine or stool leaks out without your cat choosing to go. You may notice a wet patch on the bed where your cat was sleeping, urine dribbling down the back legs, or stool left behind after your cat stands up. Some cats wake up startled and groom the wet area. This is different from inappropriate elimination, where a cat deliberately urinates or defecates outside the litter box. A cat with a behavior problem usually picks a specific spot and uses a normal posture. A cat with incontinence leaks where it rests and often seems unaware it happened. It also helps to know what is normal. Healthy older cats may sleep more and drink a bit more, but they should still control their bladder and bowels. Aging itself is not a disease, and many conditions that affect older cats can be managed once they are found [1]. So a new leak is a signal to look for a cause, not something to accept. ## Why Is My Senior Cat Peeing in Sleep? There are several common explanations, and more than one can be present at the same time. A change in elimination behavior is often one of the early signs of physical disease, and it can also make an existing behavioral problem worse [2]. Your veterinarian's first job is to sort out whether the cause is medical, behavioral, or both [2]. | Cause | Typical clues | How urgent | |---|---|---| | Urinary tract infection | Frequent small pees, straining, licking the genital area, strong odor, accidents in sleep | See a vet within a day or two | | Kidney disease | Senior cat pees a lot, drinks more, weight loss, dilute urine, night accidents | See a vet soon, within days | | Arthritis or mobility pain | Stiff walking, trouble squatting, accidents near the box or on soft beds | Routine visit, but sooner if pain seems bad | | Cognitive dysfunction | Confusion, night vocalizing, staring at walls, forgetting litter box habits | Routine visit | | Nerve or sphincter problems | Constant dribbling, wet bedding, urine scalding on the skin | See a vet soon | | Diabetes or thyroid disease | Big appetite with weight loss, heavy drinking and urination | See a vet soon | | Litter box or stress issues | Cat avoids the box, box is dirty, small, or in a busy spot | Routine visit, adjust at home now | ### Urinary Tract Infection A urinary tract infection is one of the most treatable causes of leaking. Bacteria inflame the bladder lining, so your cat feels urgency and may leak before reaching the box. Older cats are more prone to infections, especially if they have kidney disease or diabetes. A urine test confirms the diagnosis, and treatment usually involves antibiotics chosen by your veterinarian. ### Kidney Disease Kidney disease is very common in senior cats. Damaged kidneys cannot concentrate urine well, so your cat produces large volumes of dilute urine. That is why a senior cat pees a lot, drinks more, and may leak at night when the bladder fills faster than usual. A blood panel and urine test show how well the kidneys are working. If your cat is peeing large amounts, see [Cat Urinating Small Amounts Frequently: What It Means and Next Steps](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-urinating-small-amounts-frequently) for the opposite pattern, which can point to blockage. ### Arthritis and Mobility Problems Arthritis is easy to miss because cats hide pain well. A stiff cat may struggle to climb into a high-sided box or to squat properly. Some cats simply stop trying and go where they are, including on the bed. Soft bedding can also be hard to get off quickly. If your cat seems stiff or slow, see [Caring For Senior Cats](/knowledge/veterinary-medicine/clinical-methods/caring-for-senior-cats) for ways to make daily life easier. ### Cognitive Dysfunction Some senior cats develop changes in memory and awareness similar to dementia. A cat with cognitive decline may forget where the box is, especially at night, or may sleep so deeply that urine leaks. Research on clinically healthy senior cats has linked body condition and inflammatory markers to age-related behavioral and cognitive changes, which suggests these changes have a physical basis worth discussing with your vet [3]. ### Nerve and Sphincter Problems The bladder has a sphincter muscle that holds urine in. If the nerves controlling it are damaged, or the sphincter itself is weak, urine leaks out continuously. This can follow spinal problems, nerve injury, or birth defects of the urinary tract. One report described a young cat with genitourinary dysplasia and urinary incontinence that was managed with surgery and an artificial urethral sphincter, with near-total continence achieved [4]. That case involved a young cat, but it shows that sphincter problems are a real, treatable category. ### Diabetes and Other Hormonal Disease Diabetes and an overactive thyroid both cause heavy drinking and heavy urination. A cat with either condition may leak at night simply because the bladder is always full. Blood tests identify these problems, and both are manageable with treatment. ### Litter Box and Stress Factors Sometimes the box itself is the problem. A large survey of over 3,000 cats found that the number of other pets in the home, the cat's age, and the number, type, and location of litter boxes, the litter type, and how often the box was scooped and fully changed all mattered for house-soiling [5]. A separate study found that cats preferred boxes measuring at least 50 cm and clumping clay litter, and that providing this combination improved house-soiling and reduced unhappy behaviors during elimination [6]. If your cat is peeing on the bed, see [Cat Peeing on the Bed: Medical or Behavioral?](/knowledge/veterinary-medicine/anxiety-and-behavior-support/cat-peeing-on-bed-medical-behavioral) for a fuller look at both sides. ## Why Is My Senior Cat Pooping on the Bed? A senior cat pooping on bed surfaces usually has a different set of causes than urine leaking, though they overlap. - Arthritis and pain: A cat who cannot squat comfortably may defecate while lying down or right after standing. - Constipation: Hard stool builds up, stretches the colon, and can cause stool to leak around the blockage. This is called overflow incontinence. - Nerve damage: Problems in the lower spine or pelvic nerves reduce the ability to control the anal sphincter. - Cognitive dysfunction: Confused cats may not recognize the box or may not wake up in time. - Intestinal disease: Inflammation or parasites can cause urgency and accidents. - Litter box problems: A dirty, small, or hard-to-reach box is a common trigger [5][6]. If your cat is pooping on the bed and also straining or passing very hard stool, call your veterinarian. Constipation in senior cats can become a serious problem if it is not treated. ## Red Flags That Mean Emergency Care Now Some signs cannot wait. Call an emergency veterinary hospital right away if you see any of these. - Your cat is straining to pee and producing little or no urine. This can mean a urethral blockage, which is fatal within a day or two if untreated. See [Cat Straining To Pee](/knowledge/veterinary-medicine/behavior/cat-straining-to-pee) for more detail. - Your cat is crying out while trying to urinate. - There is blood in the urine or stool, or the urine smells strongly abnormal. - Your cat is vomiting, weak, collapsed, or breathing fast. - Your cat cannot stand or has lost the use of the back legs. - Your cat has not urinated in 12 to 24 hours. - Your cat's belly looks swollen and feels hard. For poison exposure, call the ASPCA Animal Poison Control Center at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661. These lines may charge a consultation fee. ## Safe Things You Can Do at Home While You Wait You cannot treat incontinence at home, but you can protect your cat and gather useful information. - Do not restrict water. Unless your veterinarian tells you otherwise, free access to fresh water is safer, especially if kidney disease is possible. - Add extra litter boxes. Place them on every floor your cat uses, and choose low-sided boxes that are easy to enter. - Keep boxes clean. Scoop at least once a day and fully change the litter regularly, since hygiene affects house-soiling [5]. - Try a larger box with clumping clay litter. Cats in one study preferred boxes at least 50 cm long with clumping clay litter, and this improved elimination behavior [6]. - Use waterproof pads on the bed. Wash soiled bedding with an enzymatic cleaner to remove odor. - Keep a simple log. Note when accidents happen, how much your cat drinks, and whether the urine volume looks large or small. This helps your veterinarian. - Do not punish your cat. Accidents from incontinence are not misbehavior, and punishment adds stress that can worsen the problem [2]. - Do not give human medications. Never give your cat pain relievers or antibiotics meant for people. Your veterinarian calculates any dose from your cat's weight and health. ## What Your Veterinarian Will Check and Test Your veterinarian will start with a full physical exam, including feeling your cat's bladder, checking the spine and joints, and looking at the skin around the rear end for urine scalding. They will ask about drinking, appetite, weight change, and litter box habits. Expect some of these tests: - Urine test: Checks for infection, blood, crystals, and how well the urine is concentrated. - Urine culture: Identifies the exact bacteria if an infection is present. - Blood panel: Screens kidney values, blood sugar, thyroid hormone, and electrolytes. - Blood pressure: High blood pressure often goes with kidney disease. - X-rays or ultrasound: Looks at bladder stones, the kidneys, the spine, and the colon. - Neurologic exam: Checks nerve function in the back legs and tail. Treatment depends on the cause. Infections get antibiotics. Kidney disease gets diet and hydration support. Arthritis gets pain control and home changes. Constipation gets stool softeners or other medication. Sphincter weakness may need medication or, in some cases, surgery [4]. Your veterinarian sets the plan and dose for your individual cat. ## Preventing and Monitoring Problems in Senior Cats You cannot prevent every cause of incontinence, but you can catch problems earlier. - Schedule twice-yearly wellness exams for cats over 10. Early detection is the main goal of senior care [1]. - Bring a urine sample to routine visits if your vet asks. It is one of the cheapest and most informative tests. - Watch drinking and urination patterns. A sudden increase in either is a reason to call. - Keep boxes easy to reach. Low sides, short distances, and good lighting help arthritic and confused cats. - Manage weight and body condition. Body condition has been linked to cognitive and behavioral changes in senior cats, so keeping your cat lean may help [3]. - Ask about pain control if your cat seems stiff. Many owners are surprised how much arthritis treatment improves litter box use. ## Limitations and When to Contact a Veterinarian This article cannot tell you what is causing your cat's accidents. Only a veterinarian who examines your cat and runs tests can do that. Individual cases always need a veterinarian's judgment. Contact your veterinarian the same day if your cat has new incontinence, is straining, has blood in urine or stool, or is drinking and urinating much more than usual. Go to an emergency clinic now if your cat cannot urinate, is crying in pain, is vomiting, is weak or collapsed, or has lost the use of the back legs. Schedule a routine visit soon if the accidents are mild but ongoing, if your cat seems stiff, or if you notice confusion or night restlessness. ## Frequently Asked Questions ### Is it normal for an old cat to pee in its sleep? No. Leaking urine during sleep is not a normal part of aging. It usually means a medical problem such as an infection, kidney disease, arthritis, or a weak urinary sphincter, and it should be checked by a veterinarian. ### Can a urinary tract infection cause my cat to leak urine? Yes. A bladder infection causes inflammation and urgency, so a cat may leak before reaching the litter box. A urine test confirms the infection, and most cats improve with the right antibiotic. ### Should I take away my cat's water to stop the accidents? No. Restricting water is dangerous, especially if your cat has kidney disease or diabetes. These cats need steady hydration. Talk to your veterinarian about the accidents instead of limiting fluids. ### Will my senior cat need medication for incontinence? It depends on the cause. Infections need antibiotics, arthritis needs pain control, and constipation needs stool softeners or other treatment. Some cats with sphincter weakness need daily medication, and your veterinarian will choose the drug and dose for your cat. ### Can I train my senior cat to use the litter box again? If the cause is medical, training alone will not fix it. Once the medical problem is treated, you can improve litter box use by offering large, low-sided boxes with clumping clay litter and scooping daily [5][6]. If your cat is avoiding the box for behavioral reasons, see [Why Is My Cat Peeing on the Floor Right in Front of Me?](/knowledge/veterinary-medicine/anxiety-and-behavior-support/cat-peeing-in-front-of-me) for more help. ## Related Articles - [Cat Peeing on the Bed: Medical or Behavioral?](/knowledge/veterinary-medicine/anxiety-and-behavior-support/cat-peeing-on-bed-medical-behavioral) - [Why Is My Cat Peeing on the Floor Right in Front of Me?](/knowledge/veterinary-medicine/anxiety-and-behavior-support/cat-peeing-in-front-of-me) - [Caring For Senior Cats](/knowledge/veterinary-medicine/clinical-methods/caring-for-senior-cats) - [Cat Urinating Small Amounts Frequently: What It Means and Next Steps](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-urinating-small-amounts-frequently) - [Cat Straining To Pee](/knowledge/veterinary-medicine/behavior/cat-straining-to-pee) - [Why Is My Cat Suddenly Peeing on the Couch?](/knowledge/veterinary-medicine/anxiety-and-behavior-support/cat-suddenly-peeing-on-couch) - [Senior Cat Peeing on the Floor or Bed: Why It Happens](/knowledge/veterinary-medicine/digestive-and-urinary-care/senior-cat-peeing-on-floor) - [Senior Cat Constipation, Diarrhea and Incontinence](/knowledge/veterinary-medicine/digestive-and-urinary-care/senior-cat-digestive-incontinence) - [Senior Cat UTI and Incontinence: Symptoms and Treatment](/knowledge/veterinary-medicine/digestive-and-urinary-care/senior-cat-uti-incontinence) ## References 1.
