Treating Urinary Infections in Cats: How Diet, Hydration and Supplements Can Help

A healthy urinary system in cats depends on a balanced diet to prevent issues like feline lower urinary tract disease (FLUTD), which affects the urethra and bladder of cats, creating major health risks and causing discomfort. Affected cats may scream in pain, pass very tiny amounts or strain to urinate. Some start urinating outside the litter box, usually on cool places like bathtubs or tile floors, or have blood in their urine.

Poor food choices, especially dry food, can disrupt urinary function, leading to pain, frequent urination and dangerous blockages. The right diet can help manage inflammation, support the bladder and speed up recovery, so proper food selection is needed for prevention and healing.

A study in the Journal of Feline Medicine and Surgery noted that FLUTD can lead to painful urination and blockages caused by struvite crystals that become wedged within the urethra. Researchers suggested that dry food can worsen the condition because the lower intake of water causes urine to be more concentrated, thereby increasing the risk of crystal formation.

Homemade Diet for Urinary Health

“Commercial dry cat food frequently lacks the necessary moisture and contains preservatives, fillers and incomplete nutrients,” says Marketa Jefferson, a holistic pet health coach. “A moisture-rich diet, such as homemade or raw food, is essential for preventing dehydration and reducing the risk of urinary issues like urinary blockages and FLUTD, as cats have a naturally low thirst drive.”

She recommends a diet with high-quality, species-appropriate ingredients tailored to support a cat’s urinary health. “A homemade diet gives pet owners full control over what goes into their cat’s food, ensuring it is fresh, balanced and free from unnecessary additives,” she explains. “Proper hydration is one of the most important factors in maintaining a healthy urinary system, and fresh food provides much-needed moisture that kibble lacks.”

Best Ingredients for FLUTD

“Urinary diets for cats should include high-quality animal proteins, such as deboned meat and organ meats, along with essential fatty acids like fish oil,” says Jefferson. “Adding the right vitamins and minerals is crucial, and small amounts of vegetables can also be beneficial.”

It may take some time and patience to convince cats that are used to eating kibble to switch to a homemade FLUTD diet. “In my experience with three cats, they all eventually switched to homemade food and love it now, but one of them took over a month to fully adapt,” Jefferson points out, adding that one of her cats lost five pounds after switching to a healthier homemade diet, which was a huge health improvement.

Natural Remedies for Urinary Support

Certain natural supplements can be beneficial for feline urinary health. “Rather than relying on antibiotics for urinary tract infections, I use natural remedies to support bladder health, as well as PEA [palmitoylethanolamide], a medicine that can ease discomfort and support the urinary tract,” says Jefferson. “Chinese herbs can help maintain kidney and bladder function, while cranberry extract may prevent bacteria from adhering to the urinary tract. Marshmallow root is another excellent remedy because it has anti-inflammatory properties and helps soothe bladder irritation, while vitamin C supports immune function and omega-3 fatty acids help reduce inflammation.”

Tips for Preventing FLUTD in Cats

Jefferson emphasizes that prevention starts with proper hydration and environmental management. “Eating moisture-rich FLUTD cat food is crucial for staying hydrated and flushing bacteria from the body. Keeping several water bowls around the house or using a water fountain can encourage drinking,” she explains.

Additionally, maintaining a clean litter box is essential because it promotes proper usage and allows for better urinary health monitoring. “I personally use Pretty Litter because its crystals change color in response to urine acidity and alkalinity, providing an early indication of potential health issues,” Jefferson points out.

“Minimizing household stressors can also greatly support both urinary and overall well-being,” says Jefferson. “Mental stimulation is just as important—interactive toys, scratching posts and enrichment activities help keep cats engaged and active, reducing stress levels.”

Marketa also points out the importance of monitoring urine acidity, noting, “Keeping an eye on your cat’s urine pH is crucial, especially if they are prone to urinary issues. The ideal range is between 6.5 and 7. If it reaches 8 or higher, that may signal an infection or underlying issue that needs veterinary attention.”
