Feline Urinary Obstruction

Urethral obstruction (UO) is a life‑threatening emergency that almost exclusively affects male cats. A blockage—usually from tiny mineral crystals, a urethral plug, or inflammation—prevents urine from leaving the bladder, leading quickly to pain, electrolyte collapse, and possibly death. Prompt veterinary attention, catheter relief, and intensive supportive care are non‑negotiable. Even after successful treatment, recurrence is common, so vigilant monitoring and long‑term dietary and lifestyle adjustments are essential.It All Begins Here
