Cat Arthritis: A Real-World Pain & Mobility Guide

Cat Arthritis Pain Management: A Mobility Guide

Medically reviewed by Dr. Sarah Mitchell, DVM — updated July 17, 2026. Dr. Mitchell is a small-animal veterinarian with a focus on feline preventive care and geriatric wellness. This guide follows current peer-reviewed recommendations from the American College of Veterinary Internal Medicine (ACVIM) and the Cornell Feline Health Center.

Arthritis in cats is one of the most under-diagnosed conditions in veterinary medicine. Studies referenced by the Cornell Feline Health Center suggest that more than 90% of cats over age 12 show radiographic evidence of degenerative joint disease — a figure that traces to Hardie et al., J Am Vet Med Assoc 2002, the most-cited radiographic survey of geriatric cats (100 cases, 1994–1997) — yet fewer than half of those cases are actively treated. Part of the reason: cats are extraordinarily good at hiding pain. By the time you notice stiffness or slowed movement, the disease is usually well advanced.

The good news: modern pain management can restore meaningful mobility and comfort to arthritic cats, often within weeks of starting treatment. This guide covers the medications, supplements, environmental changes, and lifestyle adjustments that make the biggest difference.

"Owners often tell me their cat 'just slowed down because she's old.' Then we treat the arthritis and they realize she wasn't old — she was in pain. Cats don't slow down for age. They slow down because something hurts, and arthritis is the most common culprit in senior cats." — Dr. Sarah Mitchell, DVM

Recognizing Arthritis in Cats

Cats don't limp the way dogs do. The signs of feline arthritis are subtle and easy to attribute to "just getting old":

• Reluctance to jump onto familiar surfaces (counter, bed, cat tree)
• Missing the jump — miscalculating and landing awkwardly
• Stiffness after rest — particularly obvious first thing in the morning
• Decreased activity — sleeping more, playing less
• Difficulty with stairs
• Reduced grooming — especially of the back and hindquarters (because it's painful to twist)
• Overgrown or broken claws — because the cat can't retract them properly during scratching
• Hiding or grumpiness — pain-related behavior changes
• Litter box accidents — painful to step into a high-sided box

If you notice any combination of these, ask your vet about a mobility exam and X-rays.

Why Cats Hide Arthritis Pain

In the wild, any sign of pain is a sign of weakness. Showing discomfort invites predators and competitors. House cats retain this instinct, which is why the early signs are behavioral rather than obvious limping. Cats simply adapt — using the chair instead of jumping to the counter, sleeping more because movement hurts, eliminating on the floor because the box is too high.

This hiding instinct means that by the time a cat shows visible pain, the disease has typically been progressing for months or years. Annual wellness exams with a focus on mobility are the best way to catch arthritis early.

Diagnosing Feline Arthritis

A definitive diagnosis requires X-rays (radiographs), but treatment often begins based on clinical signs:

• Physical examination: Palpation of the joints, range-of-motion testing, observation of how the cat walks and jumps
• X-rays: Show joint space narrowing, bone spurs (osteophytes), and remodeling consistent with osteoarthritis
• Rule-outs: Bloodwork to exclude other causes of reduced mobility (kidney disease, hyperthyroidism, diabetes) before starting NSAIDs

Owners can do their part between vet visits with simple in-home observation:

• Stair test: Time how long it takes the cat to climb a familiar set of stairs. Compare over weeks.
• Jump test: Place a treat on a low surface and a high surface. See which the cat prefers and how they approach each.
• Gait video: A short cell-phone video of the cat walking toward you is hugely useful at the vet visit.

Conventional Treatment Options

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs are the cornerstone of feline arthritis pain management. Options include:

• Meloxicam: Widely used off-label in cats; effective for many arthritis patients
• Robenacoxib (Onsior): Specifically labeled for cats in many countries; short-acting and well-tolerated
• Gabapentin: Not an NSAID, but a common adjunct for chronic neuropathic pain

Critical safety note: NEVER give a cat an over-the-counter human NSAID (ibuprofen, naproxen, aspirin). These are toxic to cats even in small doses. Use only veterinary-prescribed medications, and expect your vet to recommend periodic bloodwork — typically every 6 to 12 months — to monitor kidney function during chronic NSAID therapy, a routine requirement flagged by both the American College of Veterinary Internal Medicine (ACVIM) and the AAHA 2022 Pain Management Guidelines for Dogs and Cats.

Per the AAHA 2022 Pain Management Guidelines for Dogs and Cats, pain and inflammation are the two principal targets of chronic pain management in any species — and the feline toolkit has expanded meaningfully in the past decade.

Monoclonal Antibody Therapy (Solensia / Frunevetmab)

The newest category in feline osteoarthritis treatment is biologic therapy. Solensia (frunevetmab) is a once-monthly subcutaneous injection administered by your veterinarian and was the first drug approved by the FDA specifically to control pain associated with osteoarthritis in cats. Instead of blocking inflammation the way NSAIDs do, frunevetmab is a monoclonal antibody that binds nerve growth factor (NGF), interrupting the pain signal at its source.

In the pivotal field study by Gruen, Myers, and Lascelles, Frontiers in Veterinary Science 2021, three out of four caregivers reported improvement in their cat's signs of pain after three monthly injections. The most common adverse events in clinical trials were vomiting and injection site pain; Solensia should not be used in breeding, pregnant, or lactating queens. For cats whose pain is not adequately controlled by an NSAID alone, or who cannot tolerate NSAIDs because of kidney disease, Solensia has meaningfully expanded what is treatable.

Other Prescription Medications

• Adequan (polysulfated glycosaminoglycan): Injectable joint support, given as a series of shots
• Amantadine: NMDA-receptor antagonist sometimes used alongside NSAIDs
• Tramadol: Less commonly used in cats due to side effects, but an option in some cases

Supplements with Evidence

• Glucosamine and chondroitin: May slow cartilage deterioration over time
• Omega-3 fatty acids (EPA/DHA): Anti-inflammatory; meaningful improvement often seen after 8–12 weeks
• Green-lipped mussel extract: Evidence for pain relief in some feline arthritis studies

Environmental Modifications: The Single Biggest Difference

Even the best medications fall short without environmental support. The goal: make every part of your cat's daily life accessible without jumping.

• Steps or ramps: Place pet stairs next to your bed, sofa, and favorite perches
• Low-sided litter boxes: Cut down one side of a plastic storage box if a commercial low-entry option isn't available
• Soft, warm bedding: Memory foam beds support aching joints — try a heated bed in winter
• Raised food and water bowls: Reduce neck and back strain during meals
• Non-slip flooring: Place rugs or yoga mats on slippery hardwood — confident footing matters
• Multiple resources spread across the home: Don't make a stiff cat walk to a far-off room for water or a litter box

Physical Therapy and Complementary Therapies

For cats with significant arthritis, adjunctive therapies include:

• Therapeutic laser therapy: Often performed in-clinic; reduces inflammation and pain
• Acupuncture: Growing evidence base for feline arthritis, particularly at the Chi Institute and similar programs
• Hydrotherapy (underwater treadmill): Limited availability but excellent results in well-trained patients
• Passive range of motion: Gentle joint flexion at home, under veterinary instruction

When to See the Vet

Schedule a mobility check if:

• Your cat has missed a jump or seems reluctant to use the cat tree
• You've noticed increased sleeping or decreased grooming
• Litter box habits have changed (especially elimination outside the box)
• You can feel or hear joint creaking during normal movement

Seek urgent care if:

• Your cat is unable to use a back leg at all (possible saddle thrombus)
• Pain response is acute and dramatic (crying, hiding, refusing to move)
• A previously active cat becomes completely lethargic

Frequently Asked Questions

How quickly do arthritis medications work?

NSAIDs like meloxicam and robenacoxib work within hours to days. Solensia (frunevetmab) typically shows improvement within the first one to three monthly injections. Supplements like glucosamine and omega-3s take 4–8 weeks for full effect. Environmental modifications help immediately but are often overlooked.

Is my cat too old for treatment?

No. Feline arthritis management at age 15+ is routine in modern practice. Cats that feel well live longer, eat better, and maintain muscle mass — which in turn supports joint stability.

What's the best food for an arthritic cat?

Diets formulated for joint health (added omega-3s, glucosamine, sometimes green-lipped mussel) provide modest benefit. The more important dietary consideration is keeping the cat at a healthy weight — every extra pound stresses the joints.

Can I use CBD for my cat's arthritis?

Evidence is still emerging. CBD products marketed for pets vary widely in quality and labeled concentration. Discuss any supplement, including CBD, with your vet before starting — particularly if your cat is on other medications.

Will my cat need X-rays?

Probably, yes — at least once — to confirm the diagnosis and rule out other causes. After that, treatment is typically managed based on clinical response rather than repeated imaging.

Conclusion

Feline arthritis is common, under-diagnosed, and highly treatable. A combination of veterinary-prescribed pain relief, joint-supportive supplements, environmental modifications, and weight management restores meaningful mobility to the great majority of arthritic cats. If your cat is moving more slowly than last year, or hesitating at a familiar jump, schedule a vet visit. Pain isn't a normal part of aging, and your cat doesn't have to live with it.
