Feline Kidney Stones

Sometimes, mineral salts in your cat’s kidneys become insoluble and start to accumulate. This can lead to feline kidney stones. This is a very serious condition that requires immediate treatment.


There are various reasons why cats develop kidney stones. The most common is an improper diet. Felines that don’t drink enough water are also at risk. Other causes of kidney stones in cats include medications, other diseases, and genetic defects.


The most common sign of feline kidney stones is frequent urination. Your cat will likely strain and only pass small amounts of urine at a time. You may also notice that blood is present in the urine.

It’s also common for cats with kidney stones to start urinating in unusual places outside of their litter boxes. Other symptoms include vomiting, loss of appetite, depression, and weakness.


Diagnosis of cat kidney stones is relatively straightforward. The veterinarian will take x-rays of the kidneys to see if stones are present. If none are found, an ultrasound may be able to pick some up. The urine may also need to be tested since bladder infections commonly result from this condition.


Many cats with this health problem respond to changes in diet. This helps dissolve the stones immediately. Special medications, which can be mixed with drinks or food, can also be given. As a last resort, feline kidney stones may require surgery. If a bladder infection occurs, your cat will need to take antibiotics.


It’s best to prevent kidney stones from developing in the first place. It helps to ensure that your cat eats right and drinks plenty of water. Make sure he also stays healthy since other conditions can lead to kidney stones in felines.
