Urine problems are quite commonplace in the world of cats. From urinary tract infections to urine crystals, some minor urine problems are easily diagnosed and treated. From time to time, however, your cat may display symptoms of a more serious urinary problem. One symptom of a potentially severe medical condition in your cat is foamy or frothy urine. If your cat has foamy urine, act immediately as this could be a sign of kidney disease, cancer or liver problems.
How to Diagnose Foamy Cat Urine
Call your veterinarian. Explain your cat's situation, and set up an appointment for an exam.
Observe your cat's urinary symptoms. It may be gross, but look at the urine. Make a note of the color, smell and how foamy it is, as well as how often those symptoms are present, whether or not it always smells the same or is the same color and whether or not your cat is in pain when urinating.
Examine your cat's other symptoms. Make a note of eating habits, such as whether it is eating or avoiding food, whether its behavior has changed, whether it is sleeping more or vocalizing excessively. Look for yellowing in the whites of the eyes or on the tongue or weight loss. Make a note of anything out of the ordinary that your cat may be doing.
Attend the veterinary appointment. Present the veterinarian with all of the information you've taken regarding your cat's symptoms and condition.
Allow your veterinarian to perform diagnostic tests on your cat. Examples of tests for urinary problems include urinalysis, bloodwork, urine culture, urine protein, creatine ratio or serum biochemistry profile. The tests will help determine the exact cause and best course of treatment for the underlying cause of your cat's foamy urine.
