Arthritis in Cats: Signs, Treatment & Pain Management

Over 90% of cats older than 12 have arthritis - but most are never diagnosed. Cats hide pain extremely well, so signs are subtle: sleeping more, jumping less, and changes in grooming. The good news? New treatments like Solensia can dramatically improve quality of life.

Your cat used to leap effortlessly onto the counter. Now they hesitate, or don't try at all. You might think it's just "getting old" - but it's likely arthritis causing real pain. Here's how to recognize it and help your cat feel better.

How Common Is Arthritis in Cats?

The Shocking Statistics:

  • Cats 6+ years: ~60% have radiographic signs of arthritis
  • Cats 12+ years: Over 90% have arthritis visible on X-rays
  • Yet diagnosed: Less than 10% of arthritic cats are ever diagnosed

Why the gap? Cats are masters at hiding pain. Unlike dogs who limp, cats simply do less. Owners assume it's normal aging. Even vets can miss subtle signs during exams.

Recognizing Arthritis in Cats

Cats rarely limp or cry out in pain. Instead, watch for these behavioral changes:

Signs of Arthritis Pain in Cats

Mobility Changes:

  • • Hesitating before jumping up or down
  • • Jumping to lower heights, or in stages
  • • No longer jumping to favorite high spots
  • • Difficulty with stairs
  • • Stiffness after sleeping (especially noticeable in morning)
  • • Slower movement overall

Grooming Changes:

  • • Matted or unkempt fur (especially on back, hips, tail base)
  • • Overgrown claws (not scratching as much)
  • • Less time spent grooming

Behavior Changes:

  • • Sleeping more, less playful
  • • Avoiding interaction or petting (especially over hips/back)
  • • Irritability or aggression when touched
  • • Hiding more
  • • Accidents outside litter box (especially if box has high sides)

Activity Changes:

  • • Less hunting/play behavior
  • • Not exploring as much
  • • Reluctance to go outside (if outdoor cat)

Joints Most Commonly Affected

  • Elbows: Very common - may notice bunny-hopping down stairs
  • Hips: Difficulty jumping, reluctance to squat for litter box
  • Spine: Especially lower back - stiffness, sensitivity to touch
  • Knees (stifles): Affects jumping ability
  • Shoulders: Less common but can occur

Diagnosis

Your vet will diagnose arthritis through:

  • History: Your observations of mobility and behavior changes are crucial
  • Physical Exam: Joint palpation, range of motion, gait observation
  • X-rays: Show joint changes, bone spurs, narrowed joint spaces
  • Response to treatment: Improvement with pain medication confirms diagnosis

Note: X-ray severity doesn't always match pain level. Some cats with severe X-ray changes have mild symptoms, and vice versa.

Treatment Options

Solensia (Frunevetmab) - The Game Changer

Pro Tip

About Solensia

Solensia is a monthly injection that blocks nerve growth factor (NGF), a key driver of arthritis pain. It's the first FDA-approved treatment specifically for feline osteoarthritis pain.

  • How it works: Antibody that binds NGF, preventing pain signals
  • Administration: Injection given by your vet once monthly
  • Onset: Many cats show improvement within the first month
  • Side effects: Generally well-tolerated; occasional injection site reaction
  • Cost: $50-100 per monthly injection
  • Benefits: No pills, kidney-safe, highly effective for many cats

Other Medications

Gabapentin

Nerve pain medication. 5-10 mg/kg once or twice daily. Can cause sedation. See gabapentin guide.

Good for: Chronic pain, safe long-term

Meloxicam (Metacam)

NSAID anti-inflammatory. Short-term use only in cats. See Metacam guide.

Caution: Kidney risk with long-term use

Buprenorphine

Opioid pain reliever. Given under the tongue (transmucosal).

Good for: Acute pain flares, very effective

Joint Supplements

Glucosamine, chondroitin, omega-3s. Evidence mixed but generally safe.

May help: As add-on therapy

Home Modifications

Environmental changes can significantly improve your arthritic cat's quality of life:

Litter Box

  • • Use low-sided boxes (cut down one side if needed)
  • • One on each floor of your home
  • • Easy to get in and out without jumping
  • • Avoid covered boxes (harder to maneuver)

Accessibility

  • • Pet stairs or ramps to bed, couch, favorite spots
  • • Create "stepping stones" with furniture
  • • Raised food and water bowls (less bending)
  • • Keep essentials on one floor if possible

Comfort

  • • Heated beds (gentle warmth soothes joints)
  • • Soft, padded bedding
  • • Warm spots (sunny windows, near heating vents)
  • • Orthopedic pet beds

Grooming Help

  • • Regular gentle brushing (they can't reach as well)
  • • Trim nails frequently (less scratching)
  • • Help with matted areas carefully

Weight Management

Maintaining a healthy weight is crucial. Extra pounds put more stress on already painful joints. If your cat is overweight:

  • • Work with your vet on a weight loss plan
  • • Reduce portions gradually (crash diets are dangerous for cats)
  • • Consider prescription weight loss diet
  • • Encourage gentle play and movement
  • • Target 1-2% body weight loss per week maximum

Treatment Costs (2026)

Solensia (monthly)$50-100
Gabapentin (monthly)$15-40
X-rays (diagnosis)$150-300
Joint supplements$20-50/month
Home modifications$50-200 one-time

What to Expect with Treatment

  • Week 1-2: May see subtle improvements - more willing to move, less hesitation
  • Month 1: Noticeable improvement with Solensia or pain medications - jumping again, more active
  • Ongoing: Arthritis is managed, not cured. Treatment is typically lifelong.
  • Bad days: Weather changes, cold, and increased activity can cause flares

When to Call Your Vet

  • • Sudden worsening of mobility
  • • Cat stops eating or hiding more
  • • Vocalization or crying (unusual pain)
  • • Not responding to current treatment
  • • Side effects from medications
  • • Difficulty getting to litter box

Frequently Asked Questions

How do I know if my cat has arthritis?

Signs are often subtle: reluctance to jump, hesitating before jumping, difficulty with stairs, sleeping more, less grooming (matted fur), avoiding litter box, decreased activity, irritability when touched. Unlike dogs, cats rarely limp obviously.

How common is arthritis in cats?

Very common but underdiagnosed. Studies show 60% of cats over 6 years and over 90% of cats over 12 years have radiographic evidence of arthritis. Most cats hide pain well, so owners and even vets miss it.

What is Solensia and how does it work for cat arthritis?

Solensia (frunevetmab) is a monthly injectable antibody that blocks nerve growth factor (NGF), a key pain signal in arthritis. It's the first FDA-approved treatment specifically for feline arthritis pain. Given by your vet once monthly. Costs $50-100 per injection.

Is gabapentin good for cat arthritis?

Yes, gabapentin is commonly used for chronic arthritis pain in cats. It works on nerve pain pathways. Typical dose is 5-10 mg/kg once or twice daily. Often combined with other treatments. Can cause sedation initially.

Can cats take NSAIDs for arthritis?

Cats are very sensitive to NSAIDs, but Meloxicam (Metacam) can be used short-term in cats with normal kidney function. Long-term NSAID use in cats is controversial due to kidney risks. Solensia is often preferred for long-term management.

How can I help my arthritic cat at home?

Key modifications: low-sided litter boxes, ramps/steps to favorite spots, raised food/water bowls, heated beds, soft bedding, keeping nails trimmed, gentle brushing for matted areas, and maintaining healthy weight.
