Repeated litter trips with little or no urine in a male cat is an emergency until proven otherwise.
| Scenario | Cat urinary blockage |
|---|---|
| Vet vs poison control vs ER | This is an ER veterinary emergency, not poison control. Blocked cats can become critically ill within hours. Call the clinic while you drive. |
Narrow urethras obstruct more easily. Toxins from backup make cats critically ill within hours.
Crying in the box, licking the penis, and hiding are common clues.
No human pain meds. No forced water as a cure.
Bring a urine sample only if it does not delay leaving.
