Feline Urinary Tract Health

Feline urinary tract problems are relatively common and can involve the bladder, urethra, urine concentration, crystals, bladder stones, inflammation, stress, and individual sensitivity.

You may hear the term Feline Lower Urinary Tract Disease, or FLUTD. This is an umbrella term used to describe signs associated with a cat’s bladder and urethra. It is not a single diagnosis, and it does not tell us the underlying cause of the problem.

One of the most common causes of lower urinary tract signs in cats is Feline Idiopathic Cystitis, or FIC. This means bladder inflammation where no single clear cause, such as infection or bladder stones, has been found. Bladder and urethral inflammation can also contribute to urethral spasm, which may make urination painful or difficult, particularly in male cats. Stress, hydration, urine concentration, diet, body condition, pain, environmental factors, and individual sensitivity can all play a role.

Common signs include:

• frequent trips to the litter tray

• straining to urinate, which can sometimes be mistaken for constipation

• passing only small amounts of urine

• blood in the urine

• crying or discomfort when urinating

• urinating outside the litter tray

• over-grooming around the back end

• vomiting

• changes in behaviour, hiding, or agitation

Male cats are at particular risk of urinary obstruction because their urethra is narrow. A blocked cat may strain repeatedly but pass little or no urine. This is life-threatening and requires urgent veterinary care.

Please contact your veterinarian immediately if your cat is straining, unable to pass urine, crying in the litter tray, vomiting, collapsed, or seems very unwell.

Stress is a major factor in many cats with FLUTD. This is especially true in cats with feline idiopathic cystitis, where bladder inflammation occurs without obvious infection or stones.

Stress does not always look dramatic. It may relate to changes in routine, multi-cat household tension, indoor-only living, lack of environmental enrichment, pain, anxiety, or subtle conflict over litter trays, food bowls, resting spaces, or outdoor access.

Nutrition can support the body, but environmental and emotional wellbeing are often just as important for cats with recurring urinary tract issues.

Helpful strategies may include:

• multiple clean litter trays in quiet locations

• safe resting spaces

• predictable routines

• reducing household tension between cats

• encouraging play and natural hunting behaviours

• maintaining a lean body condition

• supporting hydration

• working closely with your vet if signs recur

Our approach is to gently remove common dietary stressors, support gut and bladder health, and replace them with moisture-rich, species-appropriate foods that better reflect what cats evolved to eat.

A well-planned raw diet may support urinary tract health by providing:

• naturally high moisture

• high-quality, species-appropriate protein

• very low carbohydrate levels

• no grains, starches, additives, or preservatives

• calcium and phosphorus from whole food animal sources, provided in a more natural nutritional matrix

• a diet that more closely reflects the moisture and macronutrient profile cats evolved to eat

For some cats, a careful raw feeding plan can be a helpful part of long-term urinary support. However, cats with a history of obstruction, bladder stones, recurrent crystals, infection, kidney disease, or other health concerns should be managed alongside their primary veterinarian.
