Cat Frequent Urination: Top Reasons Your Cat Is Peeing a Lot

Est. read time: 10 min.

Is your cat going to the litter box every few minutes? If your cat keeps going to the litter box but nothing happens, or you notice your cat peeing frequently (but with little to no urine), it may indicate a medical problem or concern that warrants a veterinarian’s attention. 

Regular vet check-ups are crucial to staying up-to-date on your cat's health, but you should still consistently monitor their behavior and health at home. If your cat starts acting out of the ordinary, such as making constant litter box trips, this may warrant a visit to the vet. 

Cat UTIs, bladder infections, or urethral obstructions are just a few of the medical conditions that can cause constant urination attempts. Your cat’s urinary health is of the utmost importance, so we’ll be discussing potential symptoms, diagnoses, and treatments of why your cat is peeing a lot.

Why is my cat going to the litter box every few minutes? 

Cats can be very particular about their litter box environment. If you're wondering what is normal cat litter box behavior or how often cats pee versus behavior that could indicate a medical problem, keep reading.

Dirty litter box

Your cat litter box may not be clean enough. If you use a traditional litter box and don’t scoop every day, your cat may be making frequent “unsatisfactory” trips to the litter box because the box isn’t as clean as your cat would prefer. 

Veterinarians emphasize that a clean litter box is essential to good cat health. There are two golden rules for owning traditional litter boxes: Scoop daily and have n+1 traditional litter boxes per cat (so if you have 2 cats, you need 2+1 litter boxes, or a total of 3). A single self-cleaning litter box, like Litter Robot 4, can accommodate up to 4 cats and removes the need for daily manual scooping.

However, even with a clean litter box or a self-cleaning litter box, if your cat keeps going to the litter box but nothing happens, there are a few medical issues that may be occurring.

Medical issues

Frequent litter box visits are often an indication of health issues. It’s important to call your vet and describe your cat’s symptoms. Your vet may ask you to bring your cat in for a proper diagnosis, or even tell you to go to an emergency clinic. We'll cover health conditions that may cause your cat to frequently visit the litter box and how to best treat it.

Possible medical issues indicated by frequent feline urination 

Feline idiopathic cystitis (FIC)


The majority of the time, your cat’s urinary symptoms are the result of feline idiopathic cystitis (sometimes called feline lower urinary tract disease or feline urologic syndrome), or a sterile inflammation of the bladder. 

Signs of FIC include, but are not limited to:

  • More than 3-4 trips to the litter box a day
  • Excessive grooming of the genital area
  • Squatting to urinate in front of you
  • Urinating in weird places, like on plastic bags, on your laundry, in the bathtub or sink
  • Discolored urine (e.g., blood-tinged)
  • Absence of large urine clumps in the litter box
  • Straining to urinate
  • Acting painful (e.g., meowing or crying out when using the litter box)
  • Abnormal-smelling urine

Cat FIC treatment

There is no medication or cure that directly treats FIC. However, there are ways to help aid and treat your cat's pain level. Your vet will provide options to relieve the discomfort of your cat, and may prescribe pain relievers or anti-inflammatory medications to ease the pain. At home, focus on a clean, healthy diet and a comfortable environment.

Urinary tract infection (UTI)


Less likely but still possible, your cat may be experiencing a urinary tract infection, or UTI. Cat UTIs are more often seen in older felines (greater than 10 years of age). With a UTI, you’re more likely to notice small amounts of foul-smelling, blood-tinged urine on the fur or in the cat carrier.

The symptoms of a cat UTI are very similar to FIC. Veterinarians rule in or out a UTI by performing a medical work-up that includes a physical exam, a urine sample, and a urine culture. 

Signs of a Cat UTI include:

  • Straining to urinate 
  • Licking genital area
  • Crying/pain while urinating
  • Blood in urine
  • Urinating around the house

Cat UTI treatment

The first step to treating a cat UTI is to visit the vet. Many times they will prescribe antibiotics to help fight the infection. It is also important  to make sure your cat is consistently drinking water to prevent dehydration and help promote the removal of bacteria and other toxins through urination.  

Feline urethral obstruction (FUO)


The symptoms of feline urethral obstruction are also similar to FIC and cat UTIs—but an FUO can be a life-threatening emergency. With an FUO, the waste that is to be removed from your cat’s kidneys builds up in the bloodstream from the inability to urinate, resulting in complications with the kidneys, electrolyte balance abnormalities, and, rarely, death.

Signs of feline urethral obstruction include:

  • Frequent urination
  • Vomiting 
  • Acting sleepy or tired
  • Blood in urine
  • Decreased appetite
  • Urinating outside the litter box

Cat FUO treatment

Feline urethral obstruction is a true medical emergency and your cat must be taken to the emergency vet as soon as you notice signs. The treatment procedure is known as catheterization, which is the passage of a tube up the urethra to relieve the obstruction. After the procedure, the best treatment is fluid therapy to replenish hydration and electrolytes, as well as any antibiotics the vet may recommend. 

Your vet will note that with an FUO, a large, distended, non-expressible bladder is present (as compared to a small, painful bladder with a UTI). This can sometimes be appreciated on a physical exam, but taking an x-ray or performing an ultrasound are more accurate (and less painful) ways to confirm this. 


Cat Constipation

If your cat keeps going to the litter box but nothing happens, you could be dealing with something other than a urinary issue. Instead, your cat could be constipated. Constipation is more often seen in middle-aged to geriatric cats (around 8+ years of age). If untreated, cat constipation can result in abnormal enlargement of the colon (called megacolon), which can be chronically difficult—and costly—to manage. Paying attention to your cat's bathroom habits and ensuring 24-hour access to clean water are essential in trying to prevent this. 

Causes of cat constipation include:

  • Insufficient fiber
  • Anxiety or stress
  • Kidney issues
  • Dry food diet

Signs of cat constipation include:

  • Decreased appetite
  • Hiding
  • Vomiting
  • Stiff walking
  • Weight loss

Inflammatory bowel disease (IBD)


On the other hand, your cat going to the litter box every few minutes with diarrhea could be a sign of inflammatory bowel disease. IBD in cats is similar to irritable bowel syndrome (IBS) or Crohn’s disease in humans. Another prominent sign of IBD in cats is vomiting.

Signs of cat IBD

  • Vomiting 
  • Weight loss
  • Diarrhea
  • Bloody stools
  • Lethargy
  • Decreased appetite

Cat IBD treatment 

There is no cure for cat IBD, but there are steps you can take to help aid in your cat's recovery. Your vet will provide the best treatment options for your cat. At home, you can help reduce your cat’s symptoms with a clean, healthy diet and constant hydration. Make sure the environment is comfortable for your cat to reduce stress and improve relaxation.

How often do cats pee when they are healthy?

Cats typically pee two to four times per day. Going once per day or not at all may mean that your cat is dehydrated or holding their pee. How long can cats hold their pee? Unfortunately cats have been known to hold their urine for 24 to 48 hours, resulting in urine that is very concentrated and often leading to urinary-related medical issues. 

If your cat is peeing a lot more than two or three times per day, medical issues may be to blame. You’ll want to determine if your cat is actually going to the bathroom during their frequent litter box visits. 

How long can cats hold their pee? 

Cats can typically hold their pee for about 24 to 48 hours. If a cat is holding their pee for longer than this, it could indicate a health problem such as a urinary tract infection or blockage. It's essential to monitor your cat's litter box habits and seek veterinary care if you notice any changes.

What are the signs that my cat might have a urinary issue? 

Symptoms of urinary issues in cats can include frequent or unproductive trips to the litter box, excessive grooming of the genital area, urinating in unusual places, discolored or foul-smelling urine, and visible discomfort or pain during urination. If you notice any of these signs, it's important to consult with a veterinarian as soon as possible.
