When a cat urinates frequently or in large amounts, it could be due to frequent urination or an illness.

My cat keeps going to the litter box—is this frequent urination? Could they be having trouble passing urine?

Cats are prone to many urinary-related troubles and diseases. Even minor changes can be a cause for concern, right?

In this article, we will focus on frequent urination in cats, explaining in detail the causes, underlying diseases, and when to consult a veterinarian.

What is frequent urination in cats? Focus on frequency and volume

Frequent urination in cats refers to visiting the litter box many times a day.

However, the potential diseases differ depending on whether they are urinating small amounts frequently, or if they are visiting the litter box often despite having a large volume of urine.

• Small volume of urine + high frequency = Pollakiuria (frequent urination)
• Large volume of urine + high frequency = Polyuria

In this way, you can distinguish between "frequent urination" and "polyuria" based on urine volume. If you notice your cat is visiting the litter box more often, try to pay attention to the amount of urine as well.

What is the average daily urination frequency for cats?

The average cat urinates about 2 to 3 times a day. Many cats pass stool once a day.

That said, there is significant individual variation. It is a good idea to observe your cat regularly so you can notice if their frequency or volume of urination has increased compared to usual.

Causes of frequent urination in cats

The most common cause of frequent urination in cats is "cystitis", which is an inflammation of the bladder.

Cats are designed to survive on very little water, so they produce highly concentrated urine. Because of this, their kidneys and bladder are easily strained, making them susceptible to urinary tract issues.

Symptoms of cystitis-related frequent urination

For cats under 10 years old, "idiopathic cystitis", which is caused by stress or diet, is common.

In male cats, it can also be caused by urinary crystals or stones. In senior cats, bacterial infections may also be a factor.

Since symptoms can also include hematuria (blood in urine), be sure to pay attention to the color of their urine.

Lack of appetite may indicate a urethral obstruction

"Urethral obstruction" is a condition where the urethra becomes blocked by crystals or stones, making it difficult to pass urine.

This is common in male cats, who have narrower urethras, and is rarely seen in female cats.

Symptoms include frequent urination, blood in urine, loss of appetite, and signs of pain when attempting to urinate.If left untreated, it can lead to life-threatening conditions such as acute kidney failure or bladder rupture. Seek veterinary attention immediately.

Causes of polyuria in cats

When a cat experiences polyuria, they also tend to drink more water, a condition known as "polydipsia." Polydipsia in cats is often suspected to be a sign of "kidney disease".

The kidneys filter blood and excrete waste products in the urine. Water necessary for the body is reabsorbed, resulting in highly concentrated urine.

When kidney function declines due to aging or other factors, the kidneys can no longer properly filter blood or reabsorb water, resulting in dilute (watery) urine. Because the water consumed is excreted excessively, the cat's water intake increases.

If polyuria persists for several days, it may also indicate conditions such as diabetes or hyperthyroidism, in addition to kidney disease. Since symptoms are particularly difficult to spot in cases of chronic kidney disease, ensure your cat has an annual health checkup, including blood tests.

Get to know FLUTD

FLUTD, or Feline Lower Urinary Tract Disease, is a general term for various conditions affecting the urinary system from the bladder to the urethra.

Cystitis and urethral obstructions are particularly common. Symptoms include frequent urination, blood in urine, difficulty passing urine, and signs of pain during urination. Inappropriate elimination (urinating outside the box) may also be a sign of urinary discomfort.

While symptoms may sometimes disappear without treatment, the chances of recurrence are very high. To identify the underlying cause, please visit a veterinary clinic as soon as you notice any symptoms.

Summary

Frequent urination in cats may be a sign of illness.

Furthermore, frequent urination caused by cystitis is prone to recurrence. Since it is said that it can recur within a year, be proactive about preventing cystitis.

Start by reducing stress. Ensure plenty of physical activity and keep the litter box clean at all times. Increasing water intake is also important, so try topping their meals with wet food, adjusting the height of their water bowl, or adding more water stations.

Always keep an eye on your cat’s urination frequency and volume, and if you notice any changes, visit a veterinarian.

System litter boxes have become popular recently; these not only clean up automatically but can also record your cat's frequency and volume of urination.

By utilizing technology for your cat's health, we hope you can enjoy many happy, healthy years together.
