Bladder stones, medically referred to as uroliths or bladder calculi, are accumulations of minerals and other substances in the urinary bladder. Uroliths can occur in any part of a cat’s urinary tract, from the kidneys to the urethra, although the urinary bladder is the most common site of stone formation.
Bladder stones in cats must be treated to avoid reoccurring urinary tract infections, painful urination, and the development of a fatal condition known as urinary obstruction. Once a cat has been diagnosed with bladder stones, the treatment will depend on the size and amount of the stones in the bladder, and if the stones continue to form after repeated treatments.
