What Is Arthritis in Cats? What Are the Signs?

Have you noticed your cat hesitating to jump, play, or sleep in their usual positions? Subtle changes like these can be early signs of arthritis—especially in older cats.

To get the full picture on feline arthritis, we consulted two veterinarians about how to recognize it, what causes it, and the most effective ways to support a cat living with this condition.

What Is Arthritis in Cats?

Arthritis in cats is a progressive condition marked by joint inflammation, stiffness, and discomfort that gradually limits mobility. The most common form is osteoarthritis—also known as degenerative joint disease—which develops when the protective cartilage cushioning the joints wears down over time. Without this cushion, bones begin to rub against each other, causing pain, swelling, and reduced range of motion.

Osteoarthritis is far more prevalent than many owners realize. Studies show that up to 90% of cats aged 12 and older show evidence of arthritis on X-rays—even if they aren’t displaying obvious symptoms.

What Are the Signs of Arthritis in Cats?

Cats are masters at masking pain, so arthritis symptoms are often quiet and easy to overlook. You may not see a pronounced limp or hear vocalizations—but small behavioral shifts can speak volumes.

Watch for these subtle yet telling signs:

  • Hesitation or difficulty jumping onto furniture, countertops, or climbing stairs
  • Stiffness or slight limping, especially after napping or resting
  • Reduced interest in play, exploration, or interacting with family members
  • Changes in grooming habits—such as less frequent licking or missed areas (especially along the back or hindquarters)
  • Irritability, withdrawal, or uncharacteristic grumpiness
  • Increased sleeping—or choosing lower, easier-to-reach resting spots instead of favorite high perches
  • Litter box challenges, including accidents outside the box or avoidance due to difficulty stepping in and out

What Causes Arthritis in Cats?

While aging is the most common contributor, several factors can accelerate joint deterioration:

  • Aging: Natural wear and tear on cartilage increases with time.
  • Joint injuries: Past sprains, ligament damage, or fractures can lead to arthritis later in life.
  • Joint abnormalities: Conditions like hip dysplasia or luxating patella place uneven stress on joints.
  • Obesity: Excess weight significantly increases pressure on joints, raising arthritis risk.
  • Genetics: Some breeds—including Maine Coons, Siamese, Scottish Folds, Himalayans, and Persians—are predisposed to joint issues.
  • Infection or chronic inflammation: Though rare, certain systemic conditions can damage joint tissue over time.

Are Some Cats More at Risk?

Yes—certain cats face higher odds of developing arthritis:

  • Senior cats, as joint degeneration accumulates with age
  • Breeds genetically prone to skeletal or cartilage issues
  • Cats with prior joint injuries or surgeries
  • Overweight or obese cats, due to increased mechanical strain
  • Less active cats, since regular gentle movement helps maintain joint lubrication and flexibility

How Do Vets Treat Arthritis in Cats?

Diagnosis begins with a thorough veterinary evaluation. Your vet will likely:

  • Review your cat’s medical history and recent behavior changes
  • Perform a physical exam—checking for joint swelling, heat, reduced flexibility, or pain response during movement
  • Order X-rays to assess cartilage loss, bone spurs, or other structural changes

Once confirmed, arthritis management focuses on comfort, mobility, and slowing progression—not cure. A tailored plan often includes:

  • Joint supplements: Formulas containing glucosamine, chondroitin, omega-3 fatty acids, or green-lipped mussel extract may help support cartilage health and reduce low-grade inflammation.
  • Pain medication: Veterinarian-prescribed options include non-steroidal anti-inflammatories (NSAIDs) such as meloxicam or robenacoxib (Onsior), as well as gabapentin or carefully dosed opioids for more severe discomfort.
  • Injections: Solensia—a monoclonal antibody injection approved by the FDA specifically for cats—blocks pain signals at the source. Adequan, though not FDA-approved for feline use, is sometimes prescribed off-label to help protect cartilage.
  • Weight management: Even modest weight loss can dramatically ease joint stress and improve mobility.
  • Therapeutic diets: Prescription foods like FurPetVo JointCare+ Formula, FurPetVo Satiety Support, and FurPetVo MobilityBlend contain targeted nutrients—including EPA/DHA, antioxidants, and controlled calories—to support joint function and healthy body weight.
  • Surgery: In rare, advanced cases, procedures like joint fusion or replacement may be considered to restore function and relieve pain.

How Can I Help Manage My Cat’s Arthritis at Home?

Medical care is essential—but daily home support makes all the difference in your cat’s comfort and confidence.

Make Essentials Easy to Access

Cats with arthritis benefit greatly from thoughtful environmental adjustments:

  • Keep food, water, and litter boxes on the same floor level—eliminating stairs whenever possible.
  • Provide low-entry litter boxes with shallow sides or cut-out entrances.
  • Add sturdy ramps, pet stairs, or padded steps to help your cat reach beloved perches—like couches, window seats, or cat trees—without jumping.

Support Comfort and Movement

Gentle activity keeps joints supple, while warmth soothes soreness:

  • Encourage short, playful sessions with wand toys or treat puzzles—just enough to keep muscles engaged without overexertion.
  • Offer warm, orthopedic-style beds in draft-free areas; heated pads (used safely and under supervision) can also ease stiffness.
  • Brush your cat regularly—this supports circulation, helps detect new lumps or tenderness, and strengthens your bond.

How Can I Prevent Arthritis in My Cat?

While not all arthritis is preventable, proactive care significantly lowers risk and delays onset:

  • Maintain a lean, healthy weight throughout your cat’s life—starting with portion control and appropriate nutrition.
  • Encourage consistent, low-impact activity: interactive play, vertical spaces with easy access, and puzzle feeders that invite movement.
  • Feed a balanced diet rich in joint-supportive nutrients—consider introducing vet-recommended supplements early in middle age, especially for at-risk breeds.
  • Schedule regular wellness exams, where your vet can spot early mobility changes before they become limiting.

Key Takeaways

  • Arthritis is extremely common in cats—especially seniors—and often goes unnoticed until symptoms progress.
  • Signs are frequently subtle: reluctance to jump, stiffness after rest, grooming changes, irritability, or litter box avoidance.
  • Effective management combines veterinary guidance (medication, supplements, diagnostics) with thoughtful home adaptations.
  • Prevention starts early: healthy weight, regular gentle movement, and nutrition designed for lifelong joint resilience—from FurPetVo’s science-backed formulas available at furpetvo.com—can make a meaningful difference in your cat’s comfort and vitality.
