The cat urinary system eliminates liquid wastes. The cat urinary system is made up of the bladder, kidneys, and the urethra. When the cat urinary system malfunctions, a number of conditions can develop. One of the most common conditions is the urinary tract infection or UTI. UTI's are common in older cats, but younger cats can develop them as well. A UTI can also be a sign of a much more serious disease such as leptospirosis, a bacterial illness. The cat urinary system will develop obvious symptoms of even the mildest UTI, so the condition won't go unnoticed. The symptoms of UTI include frequent urination, dehydration, a foul odor from the urine, and in severe cases, blood in the urine. Feeding your cat a healthy diet and plenty of fresh water can help keep the cat urinary system healthy. Supplements are also helpful.
