The Importance of Urinary pH in Cats

A urinalysis is one of the simplest and fastest diagnostic tests, yet it can provide vital information about a patient’s health. This analysis reveals functional disorders of the kidneys and other organs, identifies inflammation, and helps detect diseases or life-threatening changes within the body. A urinalysis consists of many indicators (including UPC, GLU, PRO, BIL, URO, KET, NIT, urinary sediment, and urinary pH). Today, we’ll take a closer look at the latter.

In cats, urinary pH reflects the acid-base balance and serves as a key indicator of urinary tract and overall health. Certain types of bladder stones (uroliths) are more likely to form in alkaline urine, while others thrive in acidic environments. A healthy pH level can be maintained through regular testing, with minor deviations corrected through specialized diets and supplements. Monitoring urinary pH is also an essential preventive measure for pets that have previously suffered from urolithiasis (bladder stones). There is no single answer as to why some pets develop stones while others do not; factors such as breed, genetics, age, and diet all play a role.

The primary signs of urolithiasis include:

• Blood in the urine;
• Increased frequency of urination;
• Difficulty urinating (straining);
• Painful urination.

If you notice any of these symptoms, it is essential to visit your veterinarian immediately.
