Presenting Signs

In this condition, affected cats develop stones in their bladder. These stones may then block the narrow urethra (the tube through which urine passes from the bladder to the outside). The stones develop when the minerals potassium, magnesium and phosphorous crystalise in the urine and the crystals grow. These cats may attempt to urinate more often than normal, they may strain and it may be painful for them to urinate. The urinary tract is often infected and inflamed. Some urine may be passed through the blockage and this urine may have blood in it. If an affected cat is totally unable to urinate it is life-threatening. They may vomit, become dehydrated and weak, and have an abnormally slow heartbeat.

Cats at Risk

Males may be more at risk than females.

Treatment

Surgical and medical: in some cases if the stones are not causing obstruction, feeding of special diets may allow the stones to dissolve. If the stones do not dissolve, or they are causing obstruction, surgery is required to remove the stones.
