Cat cystitis and urinary problems: UK treatment costs
Urinary problems are common in cats and range from an uncomfortable but manageable bout of cystitis to a blocked bladder, which is a genuine emergency. Knowing which is which matters, because a male cat straining and producing no urine needs an out-of-hours vet straight away. The real prices below reflect both routine and emergency care.
The quick version
- Most feline cystitis is stress-related rather than a bacterial infection, so treatment focuses on pain relief, hydration and reducing stress.
- A true urinary infection needs a urine sample, and sometimes a culture, before the right antibiotic is chosen.
- A blocked bladder, most common in male cats, is life-threatening and needs emergency treatment, a urinary catheter and hospitalisation.
- Straining with little or no urine, crying, or a hard, painful belly means you should call an out-of-hours vet immediately.
What people actually paid
The gap: advertised vs actually paid (medians)
People reported paying 10% more than the advertised list price for blocked bladder.
List prices are advertised prices; paid figures are what people reported, often for different cases and from a small sample so far. Treat the gap as a signal, not a quote.

Why the price varies so much
The gap between a mild flare-up and a blocked bladder is enormous in cost terms. A stress-related bout of cystitis may need a consultation, pain relief and some advice on diet and water intake, whereas an obstructed cat needs emergency care, sedation, a catheter, blood tests and days of hospitalisation, which is one of the larger bills a cat owner can face. Whether you are seen in normal hours or out-of-hours, how many tests are run, and how long your cat stays in all move the figure. Practice type matters too, with corporate branches charging around 18.3% more on average than independents in the 2026 review, and vet fees up roughly 63% from 2016 to 2023.
How to pay less
- Focus on prevention, as reducing stress, encouraging water intake and the right diet can cut the frequency of flare-ups and the vet bills that come with them.
- Get your cat seen early when signs first appear, before a simple flare has any chance of becoming a full blockage.
- Ask for a written prescription for any ongoing medication or urinary diet and compare online prices.
- Consider pet insurance, since urinary emergencies can be costly and the average claim in 2024 was around £685, and compare independent and corporate practices.
Common questions
How do I know if my cat's bladder is blocked?
Warning signs are straining in the litter tray while passing little or no urine, going in and out of the tray repeatedly, crying out, licking the back end, and a hard or painful belly. A blocked cat can become very unwell within hours, so this is an emergency: contact an out-of-hours vet immediately rather than waiting to see if it improves.
Can cat cystitis clear up on its own?
Mild stress-related cystitis can settle within a few days, but it is still worth a vet visit because the signs of simple cystitis and a dangerous blockage look similar at first, particularly in male cats. A vet can confirm your cat is passing urine normally and give pain relief, which speeds up recovery.
Does my cat need antibiotics for cystitis?
Often not. Most feline cystitis is not caused by bacteria, so antibiotics do not help and are avoided unless a urine test shows a genuine infection. For the common stress-related type, treatment is about pain relief, water, litter tray management and reducing stress at home.
