Typical low$1,000

Typical high$4,000

What’s included in the range?

Full emergency treatment including exam, diagnostics, catheterization, IV fluids, and hospitalization (roughly three days); a straightforward non-surgical case runs $750-$1,500 and perineal urethrostomy surgery adds $3,000-$4,500.

What affects the price

Severity and duration of the blockage, which drive how aggressive stabilization needs to be
Length of hospitalization, usually several days of monitoring with a urinary catheter in place
Diagnostic workup: blood tests, urinalysis, X-rays or ultrasound to check for stones and kidney damage
Complications such as kidney damage or electrolyte imbalances raise the bill quickly
Repeat blockages or surgery (perineal urethrostomy) can push total costs well above $3,000

Questions to ask your vet

Is the quote for the full treatment including hospitalization days, IV fluids, and medications, or just the unblocking procedure?
How many days of hospitalization do you expect, and what is the per-day charge?
What follow-up care or prescription urinary diet will be needed, and what does that cost?
At what point would surgery (perineal urethrostomy) be recommended, and what would it add?

Frequently asked questions

Is a urinary blockage in a cat a true emergency?

Yes. A blocked cat cannot urinate, and toxins can damage the kidneys or rupture the bladder within 24 to 48 hours. If your cat is straining to urinate with little or no output, go to an emergency vet immediately.

Why is treatment so expensive?

It combines emergency diagnostics, anesthesia and urinary catheter placement, IV fluids, pain medication, and usually several days of hospitalization with monitoring. Each component is billed separately and adds up.

Will my cat need surgery?

Only some cats. If a cat re-obstructs despite medical treatment, vets may recommend perineal urethrostomy, a surgery that widens the urethral opening. It typically costs $3,000 to $4,500.
