Urinary obstruction is one of the most common and expensive emergencies in cats, especially in males. Treating it usually costs between €500 and €1,000, and if surgery is needed the bill goes higher. Here is what it really costs, why it is so expensive, and how a policy that reimburses 100% covers it.
What is urinary obstruction (FLUTD)?
Urinary obstruction is part of the FLUTD complex (feline lower urinary tract disease). The cat cannot urinate because the urethra is blocked by crystals, plugs or inflammation. It is a life-threatening emergency: without treatment within hours it can cause kidney failure and death. For symptoms and what to do, see our FLUTD in cats guide.
How much does it cost to treat urinary obstruction in a cat?
| Item | Indicative cost in Spain |
|---|---|
| Urethral catheterisation (emergency unblocking) | €150 – €300 |
| Hospitalisation with catheter (3–5 days) | €500 – €1,000 (full episode) |
| Urethrostomy (surgery for recurrent obstruction) | from ~€530 |
| Blood tests, ultrasound and follow-up | depends on the case |
| Diet and long-term management | recurring cost |
Indicative prices; they vary by clinic, region, days of hospitalisation and whether surgery is required.
Why is it so expensive?
Because it is almost never a single visit: it involves emergency unblocking, catheterisation, several days of hospitalisation with fluid therapy and monitoring, and in cats with repeated episodes, surgery (urethrostomy). On top of that, the obstruction tends to recur, so the cost can repeat. It is exactly the kind of bill — high, urgent and sometimes recurring — where good insurance makes the difference.
How Petplan covers it
Petplan reimburses 100% of the bill up to €3,100/year, at any vet, with a €45 co-pay. On an €800 urinary obstruction, you would get back €755 (€800 − €45), versus what a policy that only covers part of it would return. Take it out while your cat is healthy: pre-existing conditions are excluded by every company.
