Arthritis affects 90% of cats over 12 - and most owners never know. Cats hide pain so well they just stop jumping and sleep more. By the time you notice, joint damage is already significant. Treatment costs $30-$100/month for life.
What Causes Arthritis in Cats
Cartilage breaks down causing bone-on-bone friction and inflammation. Age is the biggest factor: 90% of cats over 12 have arthritis. Obesity, previous injuries, and joint abnormalities accelerate it.
The most underdiagnosed condition in cats
Symptoms What to Watch For
Reduced jumping or using steps. Hesitation before jumping. Sleeping more, playing less. Stiffness after resting. Difficulty with the litter box. Decreased grooming, matted coat. Irritability when touched.
Cats hide pain - look for behavior changes, not limping
Diagnosis $200-$400
X-rays ($200-$400) confirm the diagnosis and show joint space narrowing, bone spurs, and cartilage loss. Cats tense up during exams, masking pain. Sedation may be needed for accuracy.
Average $200-$400
Treatment $30-$100/month
Solensia (frunevetmab) $50-$100/month. Meloxicam or robenacoxib $15-$40/month. Joint supplements $15-$30/month. Weight management and ramps, low-entry litter boxes, heated beds help.
Average $30-$100/month ongoing
Total Cost $500-$1,500/year
Diagnosis plus ongoing pain management, supplements, and periodic vet checks. Solensia alone runs $600-$1,200/year. $500-$1,500 annually depending on treatment approach.
Certain Breeds Higher Risk
Maine Coon, Persian, Scottish Fold, and Siamese have higher rates. Scottish Folds are especially prone due to cartilage abnormalities. But any senior cat is at risk - it's nearly universal.
Chronic Lifelong Management
Arthritis is progressive and irreversible. The goal is pain control and quality of life, not cure. Early intervention slows progression and keeps cats comfortable longer.
Prevention
Keep your cat lean - every extra pound stresses joints. Stay active with gentle play. Annual senior screening after age 7 catches it early.

Insurance Traps
Arthritis is chronic and lifelong. Insurance can cover monthly treatments - if you time enrollment right.
Arthritis Coverage Basics Pre-existing
Most policies cover arthritis if enrolled before symptoms appear. Standard 14-day illness waiting period applies. Vet visits, X-rays, Solensia injections, and pain medications are typically covered.
The Senior Cat Problem Age limit
Since 90% of cats over 12 have arthritis, insuring a senior cat is nearly impossible without it being pre-existing. Enroll young - as a kitten or young adult - before arthritis develops.
Chronic Condition Value Chronic condition
At $500-$1,500/year, arthritis treatment exceeds annual deductibles. Over 5+ years, total costs reach $5,000-$10,000. Insurance delivers significant long-term value here.
Supplement Exclusions Exclusion
Many policies exclude supplements and nutraceuticals from coverage. Glucosamine/chondroitin ($15-$30/month) isn't covered. Prescription medications and Solensia injections are covered, but over-the-counter supplements usually aren't.
Common Questions
Real answers about costs, treatment, and insurance coverage.
How common is arthritis in cats?
Studies show 90% of cats over 12 have arthritis, and up to 40% of all cats have degenerative joint disease. It's the most underdiagnosed feline condition - cats hide pain so owners attribute changes to aging.
How much does arthritis treatment cost for a cat?
Expect $500-$1,500 per year: X-rays $200-$400, Solensia $50-$100/month, pain medications $15-$40/month, supplements $15-$30/month, ramps and heated beds $50-$200 one-time.
What is Solensia and how does it work for cat arthritis?
Solensia (frunevetmab) is the first FDA-approved injection for cat arthritis pain, targeting nerve growth factor. Most cats improve in 1-3 injections. $50-$100/month with fewer side effects than NSAIDs.
How can I tell if my cat has arthritis?
Watch for behavior changes, not limping. Stop jumping, sleep more, play less, hesitate before jumping. Decreased grooming, scruffy coat. Litter box avoidance if sides are high. Irritability when touched.
Can arthritis in cats be cured?
No - arthritis is progressive and irreversible. Treatment manages pain and maintains quality of life. Weight management, pain medication, supplements, and environmental changes work together.
Is arthritis painful for cats?
Yes - cats hide it well. Pain comes from inflamed joints, bone-on-bone friction, and nerve sensitization. Owners are often amazed at how much more active their cat becomes after treatment.
What breeds are most prone to arthritis?
Maine Coons, Persians, Scottish Folds, and Siamese are predisposed. Scottish Folds have a genetic cartilage mutation, making arthritis nearly inevitable. Any cat can develop it - especially with age, obesity, or joint injuries.
Does pet insurance cover cat arthritis treatment?
Most comprehensive policies cover arthritis if enrolled before symptoms appear. Insure your cat young - before subtle signs develop. Solensia, pain medications, and vet visits are typically covered. At $500-$1,500/year for 5+ years, insurance pays back significantly.
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
