Urogenital — Feline

Calcium gluconate immediately protects the myocardium from life-threatening hyperkalemic arrhythmias and buys time while insulin-dextrose, fluids, and relief of the obstruction lower potassium. Anesthetizing an unstabilized hyperkalemic cat risks cardiac arrest. Feeding a renal therapeutic diet restricted in phosphorus (with modified protein and added omega-3s) is the intervention most consistently shown to extend survival and reduce uremic crises in feline CKD. This is feline idiopathic cystitis, a stress-associated sterile disease. Environmental enrichment, litter box management, and dietary moisture reduce recurrence; antibiotics are inappropriate with sterile urine and surgery is reserved for obstructive disease.
