How to treat bladder stones in cats

In cats, the formation of stones ("stones") in the bladder is more frequent than in other animals. The extraordinary ability to concentrate the urine of cats, coupled with the reduced water consumption of these animals, inherited from their wild ancestors (African wild cats, who practically only took the water present in their prey), seem to be responsible. If you already know how to detect the problem, in .com we explain how to treat the calculations in the bladder in cats .

Steps to follow:


Specific diet In veterinary centers and specialized stores there are available specific foods for cats with calculation problems. They exist in dry form (I think) and humid (cans).

These foods regulate the pH of the urine, they have substances that inhibit the formation of stones and have low content in the minerals that usually form crystals.

Although most of these foods are currently polyvalent, that is, they work well for different types of calculations, it is recommended to carry out a urine test beforehand to determine exactly the type of calculation and decide the most appropriate feed.

Be that as it may, these diets must be maintained for a long time, ideally for life, even if the symptoms disappear.


Water consumption. The abundant consumption of water reduces the formation of stones. Some ways to achieve this are to change the place drinkers regularly, increase the number of these or provide wet food.


Antibiotics The use of antibiotics is recommended to treat the associated urine infection or, if there is none, to prevent it.

The most suitable antibiotic will be the one that indicates the antibiogram, which is a laboratory test that is done to know which antibiotic in particular is useful for the bacteria responsible for the infection.

If no antibiogram has been performed or if they are used preventively, antibiotics of the quinolone group are usually used, the most common being enrofloxacin at a dose of 5 mg / kg, once a day, which your veterinarian will prescribe for a minimum of 15 days.

It is necessary to follow exactly the indications of the veterinarian regarding the dosage and do not forget that quinolones should not be administered in puppies .


Anti-inflammatories Its role is essential, since they reduce inflammation by reducing the risk of obstructions, and by being analgesic they make the cat feel better and eat and drink more.

It should be noted that non-steroidal anti-inflammatory drugs (NSAIDs) used in people such as ibuprofen, acetylsalicylic acid (aspirin) or paracetamol are very toxic in cats.

In cats, meloxicam, carprofen and robenacoxib can be used with relative safety.


Surgery. If all the above does not work, if there are serious risks of obstruction or if the calculation is too large to go out by itself, there is no other recourse than to resort to a surgical operation to remove it.


It is recommended to take the cat at least twice a year to the veterinarian for a review.
