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.
- From September 2026, written prescription fees are capped at £21 and practices must publish their prices, which helps when buying medicines elsewhere.
What people actually paid
Why the price varies so much
The cost is driven 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 the treatment of any other age-related conditions alongside the arthritis. Location and practice type matter as well, with corporate-owned 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
- 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.
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.
