Urinary Blockage Red Flags: Straining Without Urine Is an Emergency

Classic signs: repeated litter box trips producing no urine or a few drops, crying while squatting, genital licking, a tense painful abdomen, and later vomiting and depression. Male cats' narrow urethras block more easily, but females can obstruct too. It is often mistaken for constipation; the deciding check is whether new urine clumps appear.

After complete blockage, toxins and potassium accumulate fast, with acute kidney injury and fatal arrhythmias possible within 24-48 hours. This is an hours-level emergency, not an observe-overnight problem. Go to a clinic immediately, keep the cat warm and handled minimally, and never try expressing the bladder or dosing at home.

Veterinary care typically involves sedated catheterization, hospitalization with fluids and electrolyte correction, as the clinic decides. After discharge, follow prescription diet, hydration, and stress-reduction plans with scheduled rechecks; recurrence is common, so home management focuses on water, weight, and stress under an individualized vet plan.
