Initial treatment runs $1,200–$5,500 with catheterization and 1–3 days hospitalization. PU surgery for recurrent blockages adds $2,500–$5,000+.

A blocked male cat is a life-threatening emergency. Without treatment, kidney failure can occur within 24–48 hours. If your cat is straining in the litter box, vocalizing, vomiting, or won't pee — go to the ER now. Do not wait until morning.

Why some cats need PU surgery

Cats who block once have a high recurrence risk. Perineal urethrostomy (PU) surgery widens the urethra and reduces re-blockage. It's a major surgery and should be done at a clinic experienced with the procedure.

Long-term cost

  • Prescription urinary diet: $30–$90/month indefinitely
  • Recheck bloodwork: every 3–6 months in the first year
  • Urinalysis: $35–$120 per visit

Insurance fit

Cat urinary blockages are one of the strongest reasons to insure male cats early. Once blocked, lower urinary tract disease becomes a pre-existing condition that most policies will exclude.

FAQ

Are female cats at risk?

Female cats can develop the same lower urinary tract disease, but blockages are far more common in males due to anatomy.

Can diet really prevent recurrence?

Often yes. Prescription urinary diets paired with increased water intake (wet food, water fountains) significantly reduce recurrence in many cats.
