Craig and I maintain which we've moved to our own property. Call your vet and describe your cat's symptoms with any of your concerns about the cat's well-being. Your veterinarian may discover changes in your cat's health that you have overlooked. It is always better to err on the side of caution. They may occur as a large, single stone or as dozens of stones the size of large grains of sand or pea gravel.
Gall stones are in the gall bladder, and kidney stones are in the kidney.
They are not the same as bladder stones. Although the kidneys and urinary bladder are both part of the urinary system, kidney stones are usually unrelated to bladder stones. Hematuria occurs because the stones mechanically irritate the bladder wall, causing bleeding from its surface. Dysuria occurs when stones obstruct the passage of urine out of the bladder. When an obstruction occurs, urine cannot pass out of the body and the abdomen becomes very painful.
