Causes
Toxins (antifreeze, lilies in cats, grapes, certain medications), urinary obstruction, heatstroke, shock, severe infections (leptospirosis).
Diagnosis
Blood tests (markedly raised urea and creatinine) and urinalysis. A rapid diagnosis is crucial.
Treatment
EMERGENCY: hospitalisation with intensive fluid therapy, treatment of the underlying cause, sometimes dialysis. If action is taken early, the kidneys can recover.
Prevention
Keep kidney-damaging toxins out of reach (antifreeze, lilies, grapes), do not self-medicate your pet, and vaccinate against leptospirosis.
