Immediate action steps
- Treat repeated litter-box trips with little or no urine as an emergency in male cats especially
- Note straining, crying, licking the penis, vomiting, or hiding
- Do not give pain medications meant for humans
- Call an ER or your veterinarian immediately and prepare to transport
- Bring a urine sample only if it does not delay leaving
Litter-box pattern
Frequent visits, straining, producing little or nothing, and vocalizing are the classic set.
Blood-tinged urine can appear before complete blockage.
Systemic decline
Vomiting, lethargy, hiding, and a painful belly mean you are late in the timeline — go now.
Do not wait for a morning appointment.
