Urinary Problems in Cats by Heather Gleaton D.V.M. Holly Tree Animal Hospital www.carolinapaws/hollytree

FUS (feline urologic syndrome), or FLUTD (feline lower urinary tract disease), is a syndrome consisting of the formation of crystals/stones and mucous plugs with or without a urinary tract infection (UTI). Cats are unique in their ability to form a specific type of crystal/stone (struvite) without an underlying UTI, unlike dogs, in which the UTI causes the stone/crystal formation. Male, neutered cats are the most commonly affected by this disease but it can occur in either gender whether they are neutered or not.

The most consistent symptoms to watch for include straining to urinate, blood in the urine, urinating small amounts frequently, and urinating outside of the litterbox. If you notice these symptoms it is very important to see your veterinarian. If left untreated, your cat's urethra can obstruct with crystals and/or stones causing inability to urinate which is a life-threatening emergency.

Treatment for this syndrome consists of changing your cat's diet to one low in magnesium, ammonium, and phosphorous (the components of struvite crystals) and with a urinary acidifier which will help crystal/stone dissolution and prevent their recurrence. Antibiotics may be needed based on whether or not there is a compounding UTI. If your cat is blocked it will require hospitalization and intensive treatment.

FUS/FLUTD is a controllable disease if the diet guidelines are followed and your cat is monitored for a recurrence of clinical signs. There are several different diets available through your veterinarian if your cat is finicky. Store-bought urinary tract diets are not formulated to the point that they help to control this disease without causing calcium oxalate stones to develop so please see your veterinarian for your cat's food.
