Emergency warning
Go to an emergency veterinarian immediately
A suspected urinary obstruction is a true emergency. Do not wait for an online assessment or try to treat it at home. Call the emergency clinic while preparing to leave.
- Repeated straining with little or no urine
- Frequent litter-box trips, crying, or agitation
- Licking the genital area repeatedly
- Vomiting, hiding, weakness, or a painful abdomen
- A male cat showing any combination of these signs
If your cat is not producing urine, contact an emergency clinic now
PetAider can help organize the history, but it should not delay emergency veterinary care for a possible urinary obstruction.
What this could mean
Urinary signs may come from inflammation, stones, infection, or a urethral blockage. Owners cannot reliably distinguish these causes at home.
A complete obstruction prevents normal urine flow and can quickly cause dangerous electrolyte and toxin buildup. A veterinarian must confirm and relieve the problem.
What to tell the emergency clinic
- When you last saw a normal amount of urine
- How often the cat is entering the litter box
- Whether any drops, blood, or urine are produced
- Vomiting, appetite, energy, vocalizing, or hiding
- Previous urinary problems or prescription diet
- Age, sex, medications, and known conditions
Cost planning
Possible veterinary costs

- Sedation and urinary catheter placement
- IV fluids and multiple days of hospitalization
- Surgery or intensive care in complicated cases
Cost ranges are estimates only and vary by country, region, clinic, urgency, diagnostics, treatment, hospitalization, taxes, and insurance.

Frequently asked questions
Questions pet owners commonly ask
General guidance only. A veterinarian can evaluate your individual pet and confirm the cause.
Can I wait until morning if my cat is straining but seems alert?
No. Repeated straining with little or no urine may be an obstruction. Contact an emergency veterinarian immediately.
Is this only an emergency for male cats?
Male cats are at higher risk of complete obstruction, but any cat with painful straining or little to no urine needs urgent veterinary evaluation.
Could it just be constipation?
Urinary straining and constipation can look similar. Because urinary obstruction is life-threatening, a veterinarian should assess the cat promptly.
What treatment may be needed?
Treatment depends on the examination and tests. An obstructed cat may need sedation, catheterization, IV fluids, monitoring, and hospitalization.
