Arthritis in cats is cheap to treat badly and expensive to treat well, and the gap is a monthly bill of 30–60 versus 300 and up. The core of a good plan is one NSAID at 30–60 a month plus bloodwork twice a year; everything else — joint support at 25–50, physiotherapy at 200–400 for a course of 4–6 sessions, and 100–300 of home changes — is added in stages as the cat tells you it is needed.
The monthly base: an NSAID and two blood tests a year
Meloxicam oral suspension or robenacoxib tablets run 30–60 a month for a 4–5 kg cat, and the liquid is easier to dose at 0.1–0.15 ml per kg on the first day then 0.05 ml per kg. The drug is not the expensive part; the monitoring is. A chemistry panel plus CBC at 120–250 every 6–12 months is what makes long-term NSAID use safe, and a cat with kidney disease (IRIS stage 2–3) needs it every 3–6 months at 120–250 each time, which pushes the annual total from 400–800 to 700–1,400.
Do not split a dog's meloxicam tablet for a cat. The doses differ by a factor of 5–10 and the margin is narrow; a 4 kg cat given a 1.5 mg dog tablet is in the overdose range. Ask for the feline formulation, or for the injectable given in clinic every 4–6 weeks at 40–90 a visit.
The injectable route: 60–120 a month
Monoclonal antibody therapy against nerve growth factor is given as a subcutaneous injection in clinic every 4 weeks, 60–120 per dose, and it does not load the kidneys or the liver, which makes it the default for cats that cannot take an NSAID. The catch is that it must be given by a vet: 12 visits a year, each with a 20–40 exam or nurse fee if it is not bundled, so the real annual cost is 720–1,440 plus 0–480 in visit fees. Ask whether the practice bundles the injection with a nurse appointment, because that single question moves the annual number by several hundred.
A second injectable option is given every 4 weeks by the same route and priced similarly, so the choice between them is a clinical one, not a financial one. Neither replaces pain relief for a flare: gabapentin at 15–40 a month, dosed 5–10 mg/kg two to three times daily, is the usual add-on and costs less than the injection by a wide margin.
Joint support: 25–50 a month, and what to skip
Omega-3 fatty acids at 25–50 a month are the supplement with the most consistent support in cats: target roughly 20–40 mg/kg of combined EPA and DHA daily, which for a 5 kg cat is 100–200 mg, so read the label for mg per capsule rather than for mg of fish oil. Green-lipped mussel and glucosamine-chondroitin products run 20–45 a month and have weaker evidence; they are cheap enough to try for 8–12 weeks and stop if there is no change in how the cat jumps.
Skip the 60–120 a month "joint and mobility" multivitamin that combines 6 ingredients at doses too low to matter, and skip anything with a proprietary blend that does not state mg per serving. A 25–35 bag of omega-3 with a stated EPA/DHA number beats a 90–120 tub without one.
Physiotherapy: 200–400 for 4–6 sessions
A rehabilitation course is 4–6 sessions at 50–90 each, so 200–400, usually weekly for the first 3 weeks then every 2 weeks. What is done in the room matters less than the 10 minutes a day you do at home: weight shifting for 30–60 seconds per limb, 5–10 slow steps over poles, and range-of-motion through the hip and stifle 10 times each side. Ask the therapist to film the home program on your phone; a written handout is forgotten by week 2.
Laser therapy, if offered, is 30–70 per session and usually sold in blocks of 6, so 180–420. Underwater treadmill work is 60–110 a session and only worth it if the cat tolerates a harness, which about half do not. Set a review at session 4: if the cat is not climbing stairs more easily by then, stop paying for sessions and spend the money on the house instead.
Home changes: 100–300 that outlast any drug
A ramp or a set of 3–4 carpeted steps to the sofa is 40–120; a litter box with a 10–12 cm cut-down front is 25–60; a heated bed is 30–80; 6–8 non-slip mats or runners on the slippery path from the bed to the bowl is 40–80. Total 135–340, and every item keeps working for years. Put the food and water at floor level, add a second water bowl within 3 m of the sleeping spot, and raise the food bowl 5–8 cm so the cat does not have to flex the wrist.
| Stage | Monthly (USD) | One-off (USD) | Year 1 total (USD) |
|---|---|---|---|
| 1: early, NSAID only | 30–60 | 0–100 | 400–800 |
| 2: NSAID, omega-3, home changes | 55–110 | 135–340 | 800–1,600 |
| 3: injectable plus gabapentin | 135–280 | 200–400 | 1,800–3,400 |
| 3 plus physiotherapy | 135–280 | 335–740 | 2,000–3,800 |
| Senior with kidney disease | 160–320 | 200–400 | 2,300–4,200 |
Region, insurance and what actually changes the number
US prices are the ranges above; the UK runs 0.75–0.85 of them in pounds, and tier-1 Chinese cities 55–70% in yuan, where meloxicam oral liquid is 100–200 yuan a month and a physiotherapy session 150–300 yuan. Insurance covers arthritis as illness after a 14–30 day waiting period, but orthopaedic conditions are commonly subject to a longer 6–12 month exclusion in year one, and any lameness documented before cover starts becomes pre-existing. Check the annual limit too: a 3,400 year is fine under a 10,000 limit and useless under a 2,000 one.
Two things change the annual number more than the drug choice: weight and muscle. A cat 0.5–1 kg over ideal carries 2–4 times that load through each hip on every jump, and a 6–8 week weight plan at no extra cost beats upgrading to a 120 a month injection. Muscle mass is the other half, and it is why 10 minutes of daily home exercise is worth more than the 6th physiotherapy session.
For the bigger picture of what a cat costs across a year, the line items here sit inside the totals in the annual cost of a cat. And if the cat is young and the stiffness started after a fall, the injury side of the same problem is covered in kitten flea treatment safety, which is where the first-year product choices and their costs are set out.
Five steps for the next 30 days
- Get a pain score and a weight on the record, then recheck both at 30 days; 0.2–0.5 kg is a measurable change.
- Start the NSAID at the label dose with a baseline chemistry panel, and book the 6-month recheck now.
- Add omega-3 with a stated EPA/DHA number, 100–200 mg a day for a 5 kg cat, and give it 8 weeks.
- Buy the ramp, the cut-down litter box and 6 mats this month: 105–260 and they never stop working.
- Film the cat jumping onto the sofa today, so month 3 has something to compare against.
Frequently asked
How much does arthritis treatment cost per month for a cat?
Stage 1 is an NSAID at 30–60 a month plus bloodwork at 120–250 every 6–12 months, so 400–800 in year one. Adding omega-3 at 25–50 and 135–340 of home changes brings it to 55–110 a month. If the cat needs the monthly injectable plus gabapentin, the monthly figure is 135–280 and year one lands at 1,800–3,400.
Is the monthly injection better than an NSAID?
It is safer for a cat with kidney or liver disease, because the monoclonal antibody is not cleared through those organs, but it costs 60–120 a dose plus 12 clinic visits a year. For a cat with normal bloodwork, an NSAID at 30–60 a month with monitoring twice a year is the cheaper first choice, and it can be combined with gabapentin at 15–40 a month for flares.
Do joint supplements actually work in cats?
Omega-3 fatty acids have the most consistent support: 20–40 mg/kg of combined EPA and DHA daily, so 100–200 mg for a 5 kg cat, at 25–50 a month. Glucosamine and green-lipped mussel products at 20–45 a month have weaker evidence and are worth an 8–12 week trial only. Skip combination products that do not state mg per serving.
