Cat arthritis treatment cost in the UK
Arthritis is far more common in older cats than many owners realise, often showing up as a cat that no longer jumps onto the windowsill or grooms as well as it used to. It cannot be cured, but the pain can be managed well, and most of the cost is ongoing medication rather than a one-off treatment. The real prices below show what UK owners pay.
The quick version
- Feline arthritis is managed long term, so the main cost is ongoing pain relief rather than a single bill.
- Options include a daily anti-inflammatory liquid, a monthly injection that targets joint pain, joint supplements and weight control.
- Cats on long-term anti-inflammatories usually need periodic blood tests to check their kidneys and liver, and this monitoring adds to the running annual cost.
- From September 2026, written prescription fees are capped at £21 and practices must publish their prices, which helps when buying medicines elsewhere.
- Corporate-owned practices charged 18.3% more on average than independents, so who owns the practice on your high street can move the bill on its own.
- Vet prices overall rose roughly 63% between 2016 and 2023, so what your cat's arthritis cost a few years ago is a poor guide to what it costs now.

Why the price varies so much
The cost is driven mainly by which treatment your cat is on and how many things it needs at once. A cat managed on a daily anti-inflammatory liquid sits at one end, while a cat on a monthly pain-relief injection plus supplements and regular monitoring sits higher. The blood tests needed to keep a cat safe on long-term anti-inflammatories add to the running total, as does treatment of any other age-related condition alongside the arthritis, such as kidney disease, which is common in the same older cats. Who owns the practice matters too. The Competition and Markets Authority found corporate-owned practices charged 18.3% more on average than independents, and many well-known local vets are now part of a small number of corporate groups rather than being independently run, so the sign above the door does not always tell you which type you are walking into. Location plays a part as well, with practices in cities and more affluent areas generally pitching prices higher than rural ones. And the starting point itself has shifted: vet fees rose about 63% between 2016 and 2023, so a price that looks steep against an old memory of vet bills may simply reflect where the market has moved to.
How to pay less
- Ask for a written prescription and buy long-term pain relief from a registered online pharmacy, often 50 to 60% cheaper and a saving of £200 to £300 a year.
- Keep your cat at a healthy weight, as excess weight worsens arthritis and can mean needing more medication.
- Compare practices and use the published price lists from September 2026, when prescription fees are capped at £21.
- Ask whether a practice health plan can cover the routine monitoring blood tests that go with long-term medication.
- Ask your vet if a cheaper joint supplement or a different formulation of the same drug would suit your cat just as well as the one first offered.
- Where you have a choice locally, weigh up an independent practice against a corporate-owned one, since independents charged less on average in the CMA's review.
Common questions
Can cat arthritis be cured?
No, arthritis is a wear-and-tear condition that cannot be reversed, but it can be managed so your cat is comfortable. A combination of pain relief, weight control, joint supplements and simple home changes, such as easy-access litter trays and steps up to favourite spots, makes a real difference to quality of life.
Can I give my cat human painkillers for arthritis?
No, and this is important. Common human painkillers such as ibuprofen and paracetamol are toxic to cats and can be fatal even in small doses. Only ever use pain relief prescribed by your vet for your cat. If your cat seems sore, book a consultation rather than reaching for anything from your own medicine cabinet.
How can I make arthritis medication more affordable?
Ask your vet for a written prescription and buy the medication from a registered online pharmacy, which is frequently much cheaper than the practice. From September 2026 practices must publish their prices and cannot charge more than £21 for a prescription, making it easier to shop around for your cat's long-term pain relief.
Is the monthly injection or the daily liquid cheaper overall?
It depends on the individual cat and how your practice prices each option, so compare both on your bill rather than assuming one is always cheaper. The liquid is bought and given at home, while the injection is given at the practice, so factor in the cost of the extra visits as well as the price of the drug itself.
Why do vet practices charge such different prices for the same arthritis medication?
A large part of the gap comes down to ownership. Corporate-owned practices charged 18.3% more on average than independents, and prices also vary by region and by how a practice chooses to set its fees. Getting a written prescription lets you buy the medicine itself away from the practice, which takes some of that variation out of your control.
Do all cats with arthritis need regular blood tests?
Most cats on long-term anti-inflammatory medication need periodic blood tests to check their kidneys and liver are coping, since these drugs are processed by both organs. Your vet will set the schedule based on your cat's age and health, and it is worth asking whether a health plan at your practice covers this monitoring.
