Best UTI Supplements for Cats

If you have a cat, you are probably very familiar with their bathroom habits. You most likely clean out the litter box often and are privy to their normal routine. Regular litter box maintenance – while not a fun activity – can help you keep a close eye on your cat’s urinary health.

Many cats are prone to urinary tract issues including urinary tract infections (UTIs) or urinary diseases. And while UTI supplements for cats won’t treat active infections, they can help keep your feline’s urinary health on track. 

Let’s dive into a bit more detail about cat urinary health and go over some of the best urinary supplements for cats. 

Understanding Cat Urinary Problems

Urinary problems in cats can be caused by infection or disease. Most cats that suffer from UTIs are above the age of 10, and these infections are often secondary to another underlying endocrine issue, such as hyperthyroidism or diabetes

Cats can also suffer from other urinary tract diseases, such as FLUTD (Feline Lower Urinary Tract Disease), cystitis, or even a urethral blockage due to bladder stones.

Symptoms of UTIs and urinary issues in cats may include:

  • Trouble urinating
  • Low urine output
  • Frequent urination
  • Vocalizing while urinating
  • Straining to urinate
  • Blood in the urine 
  • Urine with a strong odor

Any of these symptoms need to be evaluated by a veterinarian as soon as possible, as some urinary tract issues can become an emergency very rapidly.

Your veterinarian will perform a physical examination and may obtain a urine sample to test for red and white blood cells, crystals, pH, and other properties. If your cat is diagnosed with a UTI, antibiotics are often administered. 

However, there are other products on the market that can support urinary tract health in your cat and prevent frequent recurrence of UTIs. 

UTI Supplements for Cats: Ingredient Overview

UTI supplements for cats often include natural ingredients that support a healthy urine pH level, decreasing the likeliness of crystal and stone formation. There are also products that support urinary tract health with natural herbs like parsley and fruits like cranberry. 

Here are some things you may see on a UTI cat supplement that may help support urinary health:

Cranberry: Cranberries contain a substance called proanthocyanidins, which might help prevent UTI-causing bacteria from sticking to the walls of the bladder and other urinary tract linings. If bacteria can’t stick, they’re likely to get expelled when your cat urinates.

Blueberry: Blueberries offer antioxidants and vitamins C and K, which can help balance the pH in your cat’s urine. 

Taurine: Taurine is an amino acid successful in preserving neutrophil bactericidal function in urine, which may help prevent the recurrence of UTIs.

Echinacea: This flowering plant is used as an herbal immune booster. Cats with a healthy immune system are better at fighting infections, including UTIs. 

Astragalus root extract: This herb can boost immune-system functionality, helping cats fight infections. 

Rehmannia powder: This herb helps support kidney function in cats.

Horsetail leaf: The horsetail plant is one of the best herbal remedies for UTI. Horsetail has astringent, diuretic, and tissue healing properties that allow it to effectively fight a urinary tract infection.
