Cat urinary calculi symptoms

The first is the most common type of urinary tract stone, cystourethritis, which is caused by inflammation of the mucous membrane of the bladder due to friction between the stone and the bladder. This can manifest as frequent urination, very little urination, even blood in the urine, crouching in the litter tray, frequent licking of the urethra and even howling when urinating. The second type is small stones or stones forming plugs blocking the urethra, in which case the cat will appear to be in a bad mood, lie in one place all the time, not want to walk, not want to eat, or even vomit. Cats with urinary stones in the bladder or ureter may have frequent urination positions, blood in the urine, or in more severe cases, shutting up and a full bladder on palpation. The only way to confirm the diagnosis is to take the cat to the vet for an X-ray and ultrasound. Many dogs and cats may still grow stones after surgery, which is an individual difference and requires not only surgery, but also medication.
