Bladder Stones in Cats
Bladder stones are rock-like deposits of minerals, crystals and organic material that are found in a cat's bladder. They can remain small in size or grow to be several millimeters in diameter, and may rub against the bladder walls, causing inflammation. Bladder stones can also lead to blockage of the urethra and can interfere with a cat's ability to urinate.
