Feline Lower Urinary Tract Disease (FLUTD) is a general term used to describe conditions affecting the bladder and urethra of cats. It can have several causes, including bladder inflammation, urinary crystals, bladder stones, infections and urethral obstruction.
Some cats may experience occasional urinary problems, while others can develop recurring episodes, particularly when stress, diet and lifestyle are contributing factors.
Signs of FLUTD
Common signs include:
- Blood in the urine
- Straining or difficulty urinating
- Frequent trips to the litter tray
- Passing only small amounts of urine
- Crying or showing pain while urinating
- Excessive licking around the genital area
- Urinating outside the litter tray
- Restlessness, hiding or changes in normal behaviour
If your cat is repeatedly trying to urinate but produces little or no urine, this can indicate a urethral blockage.
A blocked bladder is a life-threatening emergency, particularly in male cats. If you suspect your cat is unable to urinate, seek immediate veterinary treatment. Do not attempt to treat a blockage at home.
What Causes FLUTD?
There are several possible causes of urinary disease in cats. These include bladder inflammation, urinary crystals, bladder stones, urethral plugs, infections and other urinary tract conditions.
In many cats, no specific underlying disease can be identified. This is known as feline idiopathic cystitis (FIC).
Stress appears to be an important factor in many cats with FIC. Changes in the home, conflict with other cats, boredom, lack of exercise and an unsuitable environment can all contribute to stress.
Diet and Urinary Health
Diet and hydration are important considerations when supporting urinary health.
Cats naturally obtain much of their water from the food they eat. Their wild ancestors consumed prey containing a high percentage of moisture, rather than relying on a bowl of water to meet their daily needs.
Dry kibble contains very little moisture compared with fresh or wet food. Some cats do not drink enough water to compensate for this, which can result in more concentrated urine.
A moisture-rich diet can therefore be particularly beneficial for cats prone to urinary problems. Fresh, appropriately formulated food or a good-quality complete wet food can provide substantially more moisture than a dry-food-only diet.
A dry diet does not automatically cause FLUTD, as these conditions have many contributing factors, but the low moisture content of kibble is an important consideration when looking after a cat with recurring urinary problems.
A Natural Diet for Cats
Cats are obligate carnivores and are naturally adapted to a diet based primarily on animal foods.
A fresh diet can include suitable amounts of muscle meat, organ meat and appropriate sources of calcium, with other foods such as fish or egg used for variety.
However, feeding meat alone is not enough. Cats have very specific nutritional requirements, including taurine, calcium, phosphorus, essential fatty acids, vitamins and minerals.
If feeding a homemade raw diet, it should therefore be carefully formulated to ensure it is complete and balanced. Simply feeding mince, meat and bones can result in nutritional deficiencies or excesses.
The main nutritional benefit for urinary health is the high moisture content of fresh food. The aim should be to provide a complete, balanced and moisture-rich diet rather than simply replacing kibble with an unbalanced raw diet.
Encourage Plenty of Water
Increasing water intake is one of the simplest ways to support urinary health.
Try providing:
- Fresh water in several locations
- Wide, shallow water bowls
- A water fountain if your cat enjoys running water
- Moist food
- A little extra water mixed into meals if your cat accepts it
Water bowls should be kept clean and placed somewhere quiet and easily accessible.
Reduce Stress
Stress can play a significant role in recurring urinary problems, particularly feline idiopathic cystitis.
Give your cat quiet places to rest and hide, as well as elevated areas such as window perches or cat trees.
In multi-cat households, provide enough food and water stations, litter trays, sleeping areas and hiding places so that cats do not have to compete for essential resources.
Daily play and enrichment are also important. Interactive toys, food puzzles, scratching posts and secure outdoor areas such as a catio can help cats express their natural behaviours and remain active.
Litter Tray Management
Keep litter trays clean and make sure they are easy for your cat to access.
A useful guideline is to provide one litter tray per cat, plus one additional tray. Place them in quiet areas where cats can use them without being disturbed.
If a cat suddenly stops using its litter tray, do not assume the problem is simply behavioural. Pain or urinary disease can cause cats to avoid the litter tray.
What About Supplements?
Cranberry, herbs and other natural supplements may be used to help support urinary health. However, they should not be relied upon to treat FLUTD, dissolve stones or unblock a cat without lifestyle changes.
It is also not advisable to deliberately acidify your cat's urine with apple cider vinegar, vitamin C or other supplements without guidance. Different types of urinary crystals and stones form under different conditions, and altering urine pH unnecessarily can sometimes make matters worse.
If your cat has recurring urinary problems, it is better to identify the underlying cause and discuss appropriate nutritional or supplemental support to improve overall health.
When to Seek Veterinary Help
Urinary problems should never be ignored.
Contact your veterinarian if your cat develops blood in the urine, strains to urinate, frequently visits the litter tray, passes only small amounts of urine, cries while urinating or begins urinating outside the litter tray.
If your cat is unable to pass urine, seek emergency veterinary care immediately.
Supporting Natural Urinary Health
A healthy urinary tract is supported by more than just one particular food or supplement.
A natural approach should focus on providing a moisture-rich, nutritionally complete diet, encouraging water intake, maintaining a healthy body weight, providing regular exercise and reducing stress.
For cats prone to urinary problems, moving away from an exclusively dry-food diet and increasing dietary moisture can be a useful step towards supporting better hydration and healthier urine concentration.
With appropriate nutrition, plenty of moisture, a calm environment and good daily care, you can help support your cat's urinary health and overall wellbeing.
