Management of acute illness in cats. Feline urologic syndrome.

Lethargy, anorexia and vomiting suggest azotemia in cats with FUS. Clinicopathologic findings may include azotemia, hyperphosphatemia, hyperglycemia, hyperkalemia, and signs of urinary tract inflammation on urinalysis. Treatment of FUS depends on the degree of illness but generally includes removal of the urethral obstruction, bladder lavage, fluid and antibiotic therapy, and subsequent feeding of a canned, low-Mg diet with added table salt.
