Cats of any age can experience issues with their urinary tracts, and some cats are predisposed to repeat cystitis. Urinary tract issues are typically diagnosed in indoor, middle-aged male cats who are overweight and eat a dry diet, though cats of either sex and any age can experience bladder issues. It makes sense because cats evolved to get most of their hydration from their prey and did not evolve to rely on drinking a lot of water.
While chronic urinary issues can be very frustrating and concerning for a guardian, with proper diet and care, there is much hope for caring for cats with bladder issues.
The urinary tract system includes the kidneys, tubes connecting the kidneys to the bladder called ureters, the bladder, and the urethra– the tube that allows for urine to pass from the bladder out of the body. Your cat’s urinary system is broken down into the lower and upper urinary tracts. The lower urinary tract includes the bladder and urethra, and the upper urinary tract includes the kidneys and the ureters.
Your cat’s urinary system has several critical responsibilities. First, the kidneys filter the blood and get rid of waste products that are created when food is transformed into energy. The kidneys filter the blood and remove waste. Second, the urinary tract also maintains the correct balance of water, electrolytes, and salts which are needed for the body’s cells.
In addition to these two important functions, the kidney also produces erythropoietin and renin, which are important hormones that help maintain healthy blood pressure, produce red blood cells, and absorb salt correctly. Kidneys also ensure calcium to phosphorus balance.
There are numerous different urinary issues a cat can experience, and most of them are grouped under a term called Feline Lower Urinary Tract Disease (FLUTD). FLUTD actually refers to a variety of different clinical symptoms and covers a range of disorders of the urinary system from mild to serious. The signs of FLUTD are usually referred to as lower urinary tract signs. Cats with FLUTD typically show signs of difficulty and pain while urinating, increased frequency of urination, and blood in the urine. Surveys and research shows that FLUTD is the number one reason cats visit the veterinarian.
The domesticated cat originated from the desert cat and as such has the genetic ability to concentrate urine in the face of dehydration. When concentrating urine, the cat is also concentrating minerals that make up crystals in the urine that can eventually congregate into bladder stones. Concentrated urine is also more caustic and can lead to irritation of the bladder and urethra.
Urinary issues may have more than one potential cause, which makes it complex to diagnose and treat.
Some potential causes of urinary issues in cats include:
There are a wide variety of different symptoms of urinary tract issues, but there are several signs very prominent when a cat is suffering from anything involving the urinary tract.
Signs of urinary tract issues most commonly seen include:
Diet is critical in managing urinary tract issues and improving the overall health of your cat.
Ensuring your cat has enough fluids is the number one thing you can do to help your kitty. Increased water intake leads to increased urine output which is essential for urinary tract care. Cats are used to getting most of their moisture from their food such as mice and birds. So ideally, the food they consume is moist. Feeding them a high-quality meat-based diet will hydrate them properly and ensure that their urine doesn’t become either too alkaline or too acidic.
For those feeding a freeze-dried, whole food diet, it’s strongly recommended you add warm water, warm bone broth, clam juice, or sardine water etc., to rehydrate the nuggets. Freeze-drying only removes the moisture so when you rehydrate it, it becomes like the original meaty ingredients it started as. The time to rehydrate can be determined by your cats’ preferences. Some cats like crunch so you can add some dry nuggets for the preferred texture.
Whether you feed a freeze-dried diet, raw, or canned, remember the key is moisture, moisture, moisture.
Another way to help is to ensure you provide enough litter boxes that are in accessible places. This is so your cat will have constant access to them and be less likely to hold their urine. The boxes should be kept clean and should be big enough for your cat to feel comfortable using them. Clumping (scoopable) litter will help you monitor your cat’s urine production. Any changes should be noted.
There are several important aspects of a diet suitable for a cat with urinary issues:
In a cat with bladder issues, the goal is to protect the bladder and decrease the factors that contribute to struvite crystals. These nutritional goals can be supported by thoughtfully balanced whole-food ingredients.
The key to achieving this is a high-moisture diet with a high amount of good quality proteins, foods rich in antioxidants to reduce inflammation, and a diet balanced in vitamins and minerals to reduce crystal and urolith formation.
The quality and source of protein are very important for the carnivore feline suffering from urinary issues. Clean, wholesome meats and organs are easily absorbed. Plus, it provides the nutrients they can only get from meat, helping prevent nutritional imbalances. Meats also contain a lot of fluid in a form that cats are designed to utilize.
Good-quality meat, such as pasture-raised, cage-free chicken, is an optimal protein source because it contains a wide variety of vitamins, minerals, and bioavailable protein. Providing organs like chicken liver and gizzards is crucial, too, because organs are basically a bioavailable multivitamin for your cat. Your cat’s digestive system is designed to absorb almost all of the muscle meats and organs. Eggs are also a perfect source of easily absorbed protein.
The correct blend of skeletal meats (chicken), organs (liver and gizzards), and rice can nourish the carnivore without adding excessive amounts of the elements that form crystals in the urine and stones, such as calcium, phosphorus, and magnesium.
Small amounts of apple cider vinegar and cranberries provide natural compounds that help maintain proper urinary pH. Maintaining an appropriate urinary pH is an important factor in supporting overall urinary tract health and stability. Cranberries also contain proanthocyanidins that support normal urinary tract defenses.
Omega-3 fatty acids play an essential role in modulating inflammatory pathways and supporting normal cellular and tissue health. These fatty acids are especially important for maintaining urinary tract integrity and supporting overall physiologic balance.
Marine sources such as krill provide highly bioavailable omega-3 fatty acids. In addition to supporting a balanced inflammatory response, omega-3s are essential for immune function, neurologic health, and cellular stability.
Ground krill is a rich and sustainable source of these critical fatty acids and provides them in a highly absorbable form. Unlike fish oils, krill are low in the food chain, so they do not accumulate toxins that can be found in larger fish.
Though cats do not have sweet taste receptors, they can still benefit from the small inclusion of fruits in their diets. Cranberries are a well-studied component of urinary nutrition. They contain naturally occurring compounds that help maintain proper urinary pH and support normal urinary tract defenses.
Cranberries and blueberries are also rich in antioxidants, which help protect cells from oxidative stress and support normal inflammatory balance throughout the body.
Potassium chloride, lite salt, and sodium chloride, sea salt, naturally move fluids and dilute urine by increasing urination. Plus, salts improve the overall acceptance of the diet by the neophobic cat.
Glucosamine helps support the integrity of the bladder lining and overall urinary tract health.
B vitamins are added for extra support as they are critical in numerous cellular functions. These vitamins are essential to a healthy cat. The freeze-drying process can affect these fragile vitamins; therefore, they are added back to balance the diet.
Water helps with digestion, circulation, and other bodily processes like perfusion (movement of fluids through the organ). When water is flowing, it helps move crystals and other debris through the bladder, making a buildup less likely.
When you have the right nutritional framework, adding more moisture, maximizing nutrient absorption with clean, digestible proteins, and reducing excessive minerals in the cat’s diet, you not only support the proper urinary environment but minimize the likelihood of chronic urinary issues.
