Before going into detail about our top picks, let’s take a look at some of the most common urinary tract problems in cats to learn how the supplements we’ve recommended can help.

5 Common Cat Urinary Health Problems

Urinary tract disorders are fairly common in cats and many of the symptoms overlap. Straining to urinate, increased frequency of urination, and peeing outside the litter box are often an indication of urinary health problems in cats but there are numerous concerns in this category.

Some of the most common urinary health problems seen in cats include:

#1 Urinary Tract Infections (UTIs)

A urinary tract infection or UTI is an infection that affects any part of the urinary tract. This includes the ureters themselves as well as the bladder and kidneys. Because they most commonly affect the bladder, they’re also sometimes called bladder infections.

Urinary tract infections fall under the heading of feline lower urinary tract disease (FLUTD). They occur when bacteria enter the bladder through the urethra.

Common symptoms of UTIs in cats include peeing outside the litter box, frequent urination, and straining to urinate. Cats may also cry or vocalize during urination out of pain and you may notice increased odor or blood in your cat’s urine.

#2 Feline Lower Urinary Tract Disease (FLUTD)

The term feline lower urinary tract disease is used to describe a group of illnesses affecting the urinary tract in cats. These illnesses range in severity from mild to very serious and can be brought on by infections, inflammation, diet, or even behavioral problems.

FLUTD can affect cats of any age, but it’s most commonly seen in older and overweight cats. Diagnosis of feline lower urinary tract disease generally involves a review of clinical symptoms, a physical exam, and a urinalysis. In some cases, other testing such as bloodwork or x-rays may be required.

#3 Feline Idiopathic Cystitis (FIC)

One of the most common causes of FLUTD in cats, feline idiopathic cystitis (FIC) is the name given to cases of lower urinary tract disease in which the cause is unknown. Though the exact cause is unknown, stress is often a key factor in the development of FIC.

Cats with FIC often have trouble urinating but, due to bladder discomfort, make frequent attempts to urinate. It’s common to find blood in the urine of cats with FIC as well.

Many cases of FIC resolves within a few weeks with or without treatment but many veterinarians recommend treating the condition to help prevent a recurrence. Stress management is an important part of treating and preventing FIC. It’s also a good idea to keep your cat’s diet consistent.

#4 Bladder Stones

Uroliths or urinary stones are other names for bladder stones. These are rock-like collections of minerals that form in the urinary tract, causing pain and discomfort. Urinary stones can even block the urethra, causing a dangerous urinary obstruction that requires emergency veterinary care.

Bladder stones are divided into two types: struvite stones and calcium oxalate stones. Struvite stones form in alkaline (non-acidic) urine and are linked to diets high in magnesium and phosphorus. Calcium oxalate stones form in more acidic urine and tend to affect cats over 7 years of age most often. These stones can develop with calcium levels in the blood are too high, often from excessive calcium supplementation.

#5 Urinary Tract Obstruction

Male cats have a higher risk of developing urinary tract obstruction than female cats. While urinary stones are the most common cause, obstructions can also result from urethral plugs, tumors, physical abnormalities in the bladder or urethra, or lower urinary tract inflammation.

Urinary tract obstructions may be partial or complete. Unfortunately, the signs of partial obstruction can be easy to miss which may allow the condition to progress into a life-threatening complete urinary obstruction. When the urethra becomes blocked, urine can’t flow normally. The blockage can damage the lower urinary tract and cause your cat to go into kidney failure.

Early signs of urinary tract obstruction may include frequent trips to the litter box, increased vocalization, and overgrooming around the anus and urethra. Treatment generally involves medication to dissolve the stones or placement of a urinary catheter to relieve the blockage.

Do Supplements Really Help?

There’s a supplement for everything but just because a product claims to provide a certain benefit doesn’t necessarily mean that it actually does. It all comes down to the active ingredients and whether they’ve been scientifically shown to work for cats.

For example, drinking cranberry juice is a popular natural remedy for recurring UTIs in humans. Studies show that various compounds found in cranberries can help prevent bacteria from adhering to the lining of the urinary tract, kill bacteria in the bladder, and reduce inflammation. These results are not universal, however, and scientific study involving pets is limited.

Cranberry extract, a common ingredient in urinary care supplements, might provide some benefit, but it is unlikely to be more effective than antibiotics.

It’s also worth noting that many studies on the effects of cranberry juice for UTIs in humans involve a single strain of bacteria, E. coli. While E. coli can cause UTIs in pets, it isn’t the only type of bacteria that can. Efficacy also depends on the dosage and there is no standardized dose established by science.

Whether it’s nutritional supplements, probiotics, or products to support urinary wellness, it’s important to take health claims with a grain of salt.

Do your research before purchasing a supplement to make sure that the product is formulated based on scientific evidence and that it has the backing of a veterinarian. Look for products made in the USA or certified by a national regulatory agency. Choose a supplement formulated for the specific problem your cat is experiencing whether its high urinary pH, recurring UTIs, or bladder inflammation.

Most importantly, however, talk to your vet before starting a supplement to make sure it won’t interact poorly with whatever treatment your cat is already undergoing.

Bladder Formula

Buy On Chewy Buy On Amazon

Some cats simply aren’t interested in treats or chewable tablets, in which case a liquid urinary supplement might be more appropriate.

UroMAXX comes in a 6-ounce bottle with a dropper that makes it easy to administer directly into your cat’s mouth or dribbled over his food. As some cat owners have commented, however, the dropper isn’t as long as the bottle and it may not hold a full dose in one draw for larger cats.

The primary active ingredient is cranberry juice extract which helps prevent microorganisms from adhering to the lining of the urinary tract. Glucosamine supports the lining of the urinary tract as well and vitamin C helps acidify the urine, making the bladder a less favorable environment for bacteria.

This urinary supplement is safe for both cats and dogs. It’s safe for everyday use and can be used in conjunction with medications and specialty diets for urinary tract disease.

Active Ingredients

Cranberry Juice Extract, Glucosamine (as HCL), Vitamin C (as Ascorbic Acid), Herbal Extract and Amino Acid Support.

Inactive Ingredients

Glycerin, Purified Water, Natural Chicken Flavor, Potassium Sorbate, Xanthan Gum, Natural Caramel Color.

Pros

  • Easy to administer with the included dropper
  • Tasty chicken flavor
  • Helps make the urinary tract less hospitable for bacteria
  • Safe for both cats and dogs

Cons

  • Content of active ingredients isn’t listed
  • Dropper is shorter than the length of the bottle

#3 Best Powder Supplement: Solid Gold Cranberry Supplement for Urinary Tract Health

Buy On Chewy Buy On Amazon

Cranberry extract has a solid track record for helping prevent urinary tract infections in humans. Data is limited for pets, but cranberry may help prevent infectious bacteria from adhering to the lining of the urinary tract where it can make your cat sick.

This urinary supplement from Solid Gold comes in powder form. It’s designed to be sprinkled on your cat’s food in a dosage of 1/8 teaspoon for cats up to 15 pounds. The 100-gram container should last for about 160 servings.

This supplement features antioxidant-rich cranberry and blueberry as the primary active ingredients. These ingredients help maintain a healthy urine pH which may reduce the risk of urinary stones.

Active Ingredients

Cranberry Powder, Ascorbic Acid, Blueberry Powder.

Inactive Ingredients

Beef Liver Powder, Natural Flavoring, Rice Flour, Silica Aerogel.

  • Easy to administer powder form
  • Made with antioxidant-rich cranberry and blueberry

#4 Best Budget: Vet’s Best Cat Urinary Tract Support Chewables

Buy On Chewy Buy On Amazon

Treatment for urinary tract infections and other urinary concerns can be expensive. If your cat has been treated for these issues before, spending a few dollars on a urinary tract support supplement to help prevent a recurrence may be well worth it.

These chewable tablets from Vet’s Best are veterinarian-formulated with natural, plant-based ingredients for urinary health including cranberry and parsley leaf. Herbal ingredients like couch grass root and butcher’s broom root also help by flushing wastes from the body.

Note: Several of the ingredients in this formula are diuretics which could be a problem for cats with kidney disease and those taking other medications. Consult your vet before use, especially before long-term use over 7 days.

Vet’s Best recommends breaking the tablets into smaller pieces to “release the ingredients and activate the natural flavorings.” Unfortunately, the tablets are fairly hard and can be difficult to break up – it may be easier to simply crush them and sprinkle it over your cat’s food.

Active Ingredients

Cranberry Fruit, Ascorbic Acid (Vitamin C), Butcher’s Broom Root, Cornsilk, Couch Grass Root, Horsetail Leaf, Marshmallow Root, Parsley Leaf, Slippery Elm Bark Extract, Uva Ursi Leaf.

Urinary tract infections can be painful and once your cat experiences one, he’s likely to have more unless you address the underlying cause. In the meantime, a urinary tract supplement like HomeoPet could help.

This liquid cat UTI supplement is designed to be added to your cat’s food or water, though you can also drop it directly into his mouth. It’s an easy 5-drop dose for cats up to 20 pounds and the formula is safe for kittens in doses up to 2 drops at a time.

With its tasty salmon flavor, this formula seems to be appealing to cats and it’s easy to sprinkle over your pet’s food. The recommended serving size is 1 scoop (about 1 gram) for cats up to 25 pounds, so each 4-ounce container contains over 100 servings.

#7 Best For Hydration Support: Purina Pro Plan Veterinary Diets Hydra Care Supplement

Buy On Chewy Buy On Amazon

The urinary tract is designed to help remove waste from your cat’s body in the form of urine. Proper hydration is essential for healthy urinary function, but many cats don’t care much for drinking water. This supplement promotes hydration by encouraging your cat to drink more.

Packaged in 85-gram (3-ounce) pouches, this hydration care supplement looks and smells similar to a thick gravy. The liver flavor entices cats to consume the supplement and, in doing so, they take in more moisture. The formula also contains nutritional osmolytes that help the cells absorb more water.

Customers report positive results with this product and cats seem to enjoy the flavor. The cost could, however, be prohibitive for some pet parents. It’s unclear whether your cat would gain the same benefits eating a moisture-rich wet food or consuming bone broth.

Active Ingredients

None

Inactive Ingredients

Water, Whey Protein Isolate, Glycerin, Guar Gum, Liver Flavor, Potassium Chloride.

Pros

  • Appealing liver flavor and gravy-like consistency
  • Encourages cats to drink more water
  • Contains natural osmolytes to help cells absorb water

Cons

  • Contains artificial flavor
  • Expensive, some cats need 2 pouches per day

Supplements Can Help Support Urinary Health, But They Aren’t A Substitute For Treatment

There’s no replacement for sound veterinary advice. Whatever problems your cat is experiencing, it’s important to address the issue with your vet instead of trying to diagnose and treat it yourself.

While most urinary health problems are not life-threatening for cats, they can be extremely uncomfortable – even painful – and lack of treatment could cause the issue to progress into something more serious. Untreated urinary problems also frequently contribute to behavioral issues like peeing outside the litter box and increased irritability.

Treatment for urinary health concerns varies depending on the specific issue but, on top of treatment, your veterinarian may recommend giving your cat a supplement. Urinary health supplements are intended to support your cat’s ongoing urinary health and to help remedy or prevent issues that contribute to urinary issues.

Before purchasing a supplement, talk to your vet about what active ingredients to look for so you can be sure you’re supporting the critical aspect of your cat’s urinary health.
