Urinary stones are among the most common health problems in cats. And a simple, often overlooked factor plays a key role in their prevention: hydration.
What is a urinary stone in a cat?
A urinary stone is an accumulation of minerals that crystallize in a cat's urinary tract. Depending on their size and location, they can cause discomfort, pain, or even a urinary obstruction, which is a veterinary emergency.
The link between hydration and urinary stones
The more concentrated a cat's urine is, the higher the risk of mineral crystallization. Conversely, proper hydration dilutes the urine and promotes more frequent urination, which limits the contact time between minerals and the lining of the urinary tract.
This is why veterinarians often recommend, in addition to a suitable diet, encouraging water consumption as much as possible for cats prone to this type of problem.
Which cats are most at risk?
- Male cats, due to a narrower urethra
- Cats that are overweight or inactive
- Cats fed almost exclusively on dry kibble, with very low dietary water intake
- Cats that do not drink much from their bowl
These risk factors do not mean that a cat will necessarily develop stones, but they do justify paying special attention to their hydration.
Warning signs to watch for
Difficulty or pain when urinating, frequent urination in small amounts, blood in the urine, excessive licking of the genital area, or a complete absence of urine (an absolute emergency): these signs require a quick veterinary consultation.

How to encourage hydration on a daily basis
- Prioritize wet food whenever possible, as it is naturally higher in water
- Increase the number of water sources in the house
- Change the water regularly to keep it appealing
- Provide a water fountain to stimulate the cat's natural interest in moving water
In summary
Hydration alone does not prevent all urinary problems, but it remains one of the simplest and most accessible ways to reduce risks on a daily basis. In case of doubt or symptoms, professional veterinary advice is essential.
