Excessive Cat Urination

Cat urination patterns may help you determine if your pet is healthy. If the cat urinates in excess or fails to urinate normally, you should look for additional symptoms to identify the problem. Some of the most common causes of excessive cat urination include urinary tract infections, diabetes, stress or renal failure.

Urinary Tract Infection

UTI or the urinary tract infection is a condition that may be caused by bacteria that gather in the urinary tract. The infection is more common in female cats; the condition will cause a lot of pain when urinating, so the cat may cry due to pain when urinating and will also urinate more frequently in reduced amounts.

Some cats will urinate outside the litter box.


Diabetes is caused by an excess of glucose in the blood that may not be properly assimilate by the body.

Diabetes causes increased thirst, frequent urination, weight loss, bad breath and poor skin and coat condition.


Stress may cause the cat to urinate more than usual. Stress can be caused by different changes in the cat’s life, a disease or by the absence of a family member.

Renal Failure

Kidney disease or renal failure may cause excessive urination. Renal failure is more common in senior cats and may be caused by aging or may be an inherited condition.

The renal failure presents symptoms such as lack of appetite, lethargy, weight loss, bad breath, vomiting, diarrhea and the cat will drink more water. You may find your cat drinking water from all sorts of sources and he will also urinate more frequently.

Thyroid Issues

In some cases, the excessive urination may be caused by a thyroid problem. Thyroid problems may also be signaled by dry, flaky skin or oily skin and acne in the facial area. The coat will also be coarse and dull.

A cat with a thyroid problem will drink more water, consequently will urinate more frequently.

Thyroid problems are difficult to spot, but some blood tests may determine if your cat has hypo or hyperthyroidism.

Eliminating Excessive Cat Urination

The excessive cat urination behavior may be eliminated by finding the reason why the cat does this and applying suitable treatment.

UTI may be treated with antibiotics and by flushing the bacteria with lots of liquids.

Diabetes is not a treatable condition, but may be managed through insulin administration, weight loss and diet changes.

Stress may be managed through medication, pheromone diffusers or by giving more attention to your cat.

Kidney failure may be not be reversible, depending on how advanced the disease is; the cat should receive support therapy, fluid administration and medications.

You should also clean the areas where the cat has urinated, so that the cat won’t be tempted to urinate on the furniture or the walls after receiving treatment. You may use a vinegar diluted solution or enzyme based cleaners; other types of cleaners will not remove the odor.
