What kind of stones can be found in a cat's kidneys? - briefly
The most common type of stone found in a cat's kidneys is struvite, which accounts for about 80-90% of all feline urinary stones. Other types include calcium oxalate and urate stones, but they are less frequent.

Cats, like humans, can develop kidney stones, which are mineral deposits that form in the kidneys. These stones can cause discomfort, pain, and potentially serious health issues if not addressed. The types of stones found in cats' kidneys are primarily composed of different minerals.
One common type of stone is struvite stones. Struvite stones are made up of magnesium ammonium phosphate hexahydrate and typically form as a result of urinary tract infections, especially those caused by bacteria that produce urease. These bacteria break down urea in the urine, increasing the levels of ammonia and thus promoting the formation of struvite stones.
Another type of stone is calcium oxalate stones. These are composed of calcium and oxalate, which are naturally occurring substances in the body. Calcium oxalate stones can form when there is an excess of these substances in the urine, often due to dietary factors or metabolic conditions that lead to increased excretion of calcium and oxalate.
Urate stones are less common but can still occur in cats. These stones are composed of uric acid and can form when there is an imbalance in the body's purine metabolism, which is involved in the production of uric acid. Certain genetic conditions or dietary factors can contribute to the formation of urate stones.
Cystine stones are rare but possible in cats. Cystine stones form from a buildup of cystine, an amino acid, and are often associated with a genetic disorder called cystinuria. This condition affects the kidneys' ability to reabsorb cystine, leading to its excretion in high amounts and subsequent stone formation.
Understanding the type of stone is crucial for appropriate treatment. Veterinary diagnosis typically involves urinalysis, blood tests, radiographs, or ultrasound examinations to identify the composition and size of the stones. Treatment options may include dietary modifications, medications to dissolve certain types of stones, or in some cases, surgical intervention to remove the stones. Preventive measures such as maintaining a balanced diet and ensuring proper hydration can also help reduce the risk of stone formation in cats.
