A cat straining in the litter box without peeing: an emergency
Updated : October 8, 2026
A cat that cannot pee can be in life-threatening danger within hours. It happens more often in males, whose urinary tract is narrower and can become blocked.
Signs to recognize
- Repeated trips to the litter box with little or no urine
- Crying or straining when trying to urinate
- Repeated licking of the genital area
- Urine in unusual places
- Lethargy, loss of appetite, vomiting
- A sore or swollen belly
What to do
Call an open veterinary clinic right away, day or night. A urinary blockage cannot be fixed at home and must not wait until the next day. Carry your cat calmly and warm in its carrier, without giving any medication.
Do not mistake it for simply needing to pee often. If your cat spends time in the litter box without producing urine, call the clinic: staff will tell you whether to come in.
After the emergency
The vet may suggest a suitable diet and tips to reduce the risk of recurrence: fresh water at all times, clean and easy-to-reach litter boxes, less stress.
