Why Is My Cat’s Litter Box a Waterpark? How to Handle Frequent Urination in Cats


Increased urination frequency in cats, or polyuria, is a common concern for cat owners. When a cat starts peeing more often, it can indicate an underlying health issue that requires veterinary attention. This article will provide an overview of the most common causes of frequent urination in cats and what cat owners can do about it.

We’ll start by looking at potential medical issues like urinary tract infections, kidney disease, diabetes, and bladder stones. Then, we’ll explore behavioral causes. Finally, we’ll discuss treatment options and steps owners can take to prevent future instances of frequent urination.

Get Veterinary Attention

If your cat is peeing frequently or having accidents around the house, the first step should be scheduling an appointment with your veterinarian to rule out potential medical issues. An exam and testing are crucial since increased urination is often the first sign of an underlying health problem. Some common medical causes include urinary tract infections, kidney disease, diabetes, and bladder stones.

According to Petable.care, “If you find your cat peeing frequently outside the litter box, consider [getting a veterinary exam]. There are many medical conditions that can cause increased urination.”

Don’t try to guess the cause or treat it yourself without input from your vet. Catching and addressing medical problems early greatly improves the chances of successful treatment and prevention. Your vet can run tests on your cat’s urine sample and potentially identify issues like infections, organ disease, and more. Based on the exam and test results, they can then recommend an appropriate treatment plan.

While frustrating, try not to get angry at your cat for the accidents. Increased urination and peeing outside the litter box are not behavioral issues, but rather signs your cat is unwell and needs medical care. So schedule a vet appointment as soon as possible if you notice any unusual peeing habits.

Urinary Tract Infections

Urinary tract infections (UTIs) are a common medical cause of increased urinary frequency in cats [1]. UTIs occur when bacteria enter the urinary tract and multiply, causing inflammation and irritation. The most common bacteria causing UTIs in cats are E. coli, Staphylococcus, Streptococcus, and Proteus mirabilis [2].

Cats with UTIs feel the frequent urge to urinate, often straining and producing only small amounts of urine each time. The urine may contain blood, have a foul odor, or appear cloudy or discolored. UTIs can cause discomfort, pain, and secondary damage if left untreated, so veterinary care is essential.

Veterinarians diagnose UTIs through urinalysis, urine culture, and sometimes imaging tests. Treatment involves antibiotics, sometimes for several weeks, to clear the infection. Ensuring your cat drinks plenty of fluids can help flush bacteria from the urinary tract. In recurring or chronic UTIs, long-term antibiotics may be needed [3].

Kidney Disease

Kidney disease is another potential cause of frequent urination in cats. As the kidneys fail, they lose their ability to concentrate urine. This results in the production of large volumes of dilute urine, leading to frequent and urgent trips to the litter box. Some signs of kidney disease include increased thirst, weight loss, poor appetite, and vomiting. Kidney disease is commonly seen in older cats, but younger cats may also be affected. Diagnosis is made through bloodwork, urinalysis, imaging, and biopsy. Treatment depends on the cause and stage of the disease but may include fluids, medications, dietary changes, and dialysis. With early detection and proper management, many cats with kidney disease can live happily for years. However, kidney disease is a progressive condition that requires close monitoring and care.


Diabetes mellitus is a disease where the body cannot properly regulate blood sugar levels. This is often caused by a lack of insulin production or improper insulin function. Diabetes can lead to excessive thirst and frequent urination in cats.

With diabetes, glucose builds up in the bloodstream instead of being absorbed by cells for energy. The kidneys then try to filter out and excrete the excess glucose through urination. This leads to increased water intake and urine production. A diabetic cat may start urinating outside the litter box and need to pee more often just to relieve themselves of all the excess glucose.

According to the Cornell Feline Health Center, other signs of diabetes in cats include: increased appetite, weight loss, lethargy, vomiting, and weakness in the hind limbs. Diabetes requires veterinary treatment with daily insulin injections and a specialized diet. With proper management, cats can live normal lives with this chronic condition.

Bladder Stones

Bladder stones are a common cause of frequent peeing in cats. They form when minerals build up in the bladder, creating crystals that can turn into stones. These stones irritate the lining of the bladder, causing inflammation, discomfort, and the urge to urinate frequently. According to veterinarian Dr. Justine Lee, “Bladder stones (uroliths or cystic calculi) are rock-like collections of minerals that form in the urinary bladder” (source).

Cats with bladder stones will often strain while peeing, pass only small amounts of urine, and lick their genital area frequently. They may pee outside the litter box because of the urgency to urinate. Bladder stones can cause life-threatening blockages, so it’s important to get prompt veterinary treatment. Diagnosis involves analyzing urine and taking x-rays or an ultrasound. Treatment options include prescription diets to dissolve the stones, medications, and surgery to remove them.

Behavioral Causes

Sometimes frequent urination can be due to behavioral issues rather than medical ones. Common behavioral causes include:

Anxiety – Cats may urinate frequently due to stress, anxiety, or changes in their environment. This could be caused by introducing a new pet or family member, moving homes, loud noises, etc. Anxiety-related peeing often happens outside the litter box.

Litter box issues – An unclean litter box, insufficient number of boxes, or undesirable location can cause a cat to urinate elsewhere. Cats are very particular about their bathroom habits.

Marking territory – Urinating around the house can be a way for cats to mark their territory, especially if another neighborhood cat is visible outside. This is most common in unneutered male cats.

Attention-seeking – Some cats may urinate frequently to get attention from their owners. This should be discouraged by avoiding scolding and rewarding positive litter box use instead.

Stress – Changes in routine, noisy environments, new people/pets, or negative interactions can stress some cats and lead to inappropriate urination. Creating a predictable, calm environment can help.


Once the underlying cause for frequent urination is identified, the vet will prescribe appropriate treatment. This may include:

Antibiotics if there is a urinary tract infection. Antibiotics like Amoxicillin are commonly prescribed for 7-10 days. Ensure the full course is completed even if symptoms improve.

Medication if diabetes or kidney disease is the cause. This helps manage the condition. Insulin injections may be required for diabetic cats.

Surgery to remove bladder stones or crystals. This eliminates the irritation and allows normal urination.

Behavioral therapy if marking territory or stress is the cause. Pheromones, medication, environmental changes may be recommended. Seek help from an animal behaviorist.

A change in diet. Prescription food for urinary or kidney health may be recommended long-term.

Increased water consumption to dilute the urine. Additional water bowls around the home can encourage drinking.

Litter box changes like additional boxes or different litter to encourage proper use.

With treatment guided by a vet, most cats with frequent urination can be managed successfully. Don’t attempt to self-diagnose or treat without an exam as you may miss the real underlying problem.

Prevention of Frequent Urination Issues

There are several steps cat owners can take to help prevent frequent urination issues in cats:

1. Feed your cat a high-quality diet and avoid foods with fillers. A healthy diet promotes good urinary tract health. Ask your vet for diet recommendations if needed.

2. Ensure your cat always has access to fresh, clean water. Increased hydration helps dilute urine and prevent crystals. Consider getting a cat fountain if your cat does not drink enough water.

3. Clean the litter box daily. Cats prefer a clean bathroom. Use an unscented clumping litter and completely change the litter weekly.

4. Provide an extra litter box, especially if you have multiple cats. This gives more bathroom options to reduce anxiety and frequency.

5. Give your cat environmental enrichment through toys, cat trees, and playtime. A mentally stimulated cat will use the litter box appropriately.

6. Use synthetic feline pheromones like Feliway to reduce stress. Stress can cause inappropriate urination.

7. Bring your cat to the vet annually for wellness exams to screen for urinary tract disease. Early detection allows for better management of issues.

If you notice any signs of abnormal urination, bring your cat to the vet promptly for diagnosis and treatment. Addressing problems early is key to preventing recurrent issues.


In summary, frequent urination in cats can be caused by several conditions including urinary tract infections, kidney disease, diabetes, bladder stones, or behavioral issues. It’s important to get veterinary attention to identify the underlying cause through diagnostic tests. Treatment will depend on the diagnosis but may include antibiotics, medications, diet changes, or addressing behavioral triggers. Prevention focuses on providing plenty of fresh water, an appropriate diet, adequate litter boxes, and minimizing stress. If your cat is urinating frequently, don’t delay in getting veterinary attention to relieve discomfort and prevent potential complications.
