Urinary Stones (Uroliths, Calculi) in Cats

Minerals that naturally occur in urine can clump together to form tiny crystals. When crystals clump together, they form uroliths (also known as urinary stones or calculi). These stones can develop anywhere in the urinary system, including the kidney, ureter, bladder, or urethra. Certain types of stones appear to have increased in cats in recent years. The cause is not clear, but re

Not every disease is caused by infection with bacteria, viruses, or other outside agents. There are a variety of noninfectious disorders that can impair the urinary system. All of these diseases and conditions can be serious threats to the health of your cat.   Kidney Dysfunction The kidneys’ most important function is to filter waste from the blood. When this does not happen properly, waste products can bu

Most infections of the urinary system are caused by bacteria. The infection usually develops when bacteria enter the body through the urethra. The bacteria then travel to the bladder, and in some cases they set up an infection there. Sometimes bacteria continue to move up the urinary tract to the kidneys and can result in kidney infection (pyelonephritis). There are several factors that increase the risk of urinary system infection. These include problems with urine

Certain urinary tract abnormalities are inherited or congenital (present at birth). These abnormalities are caused by abnormal genes or produced by injury, disease, or exposure to toxic substances in the womb. They may or may not cause health problems later in your pet’s life. These types of abnormalities are rare, but important to consider, if your cat has urinary tract problems.   Disorders of the Kidneys

Your veterinarian can diagnose many common problems involving the urinary system by taking a medical history, performing a physical examination, and performing tests on the cat’s blood and urine. The history might include information regarding changes in how much water your pet drinks, how often it urinates, how much urine it produces, how the urine looks, and how your pet behaves. Your veterinarian will also need information about what medications your pet has taken or is curren

The urinary system or tract includes the kidneys, the ureters (tubes that connect the kidneys to the bladder), the bladder, and the urethra (the tube through which urine exits the body). The urinary system has several important functions. It gets rid of the waste products that are created when food is transformed into energy. It also maintains the correct balance of water and electrolytes (salts) needed for the body’s cells. Another key function is the production of erythropoietin and r
