Guinness the domestic cat is about 9 years old. She recently made a very serious visit to the veterinary clinic for bilateral ureteral obstruction. The ureters are the passageways for urine to pass from the kidneys to the bladder.
When this condition occurs, a cat will show signs of straining to urinate, frequent urination, lethargy, vomiting, abdominal pain, and weight loss. An affected cat may act unusual and angry as they can be in severe pain. Urinary obstruction requires emergency treatment as it can lead to kidney failure.
