• Results from a past joint injury (fracture, dislocation, ligament tear)
• Can develop immediately or years after the initial trauma

Inflammatory Arthritis

• Caused by immune-mediated disorders or infections (bacterial, viral)
• Less common but requires specific treatment approaches

Commonly Affected Joints

Arthritis frequently impacts:

• Hips (often related to hip dysplasia)
• Knees (especially if previously injured)
• Elbows & Shoulders (common in heavier cats)
• Spine (vertebral arthritis is extremely prevalent)
• Ankles (Hocks)

Prevalence and the Diagnosis Gap

Modern research confirms feline arthritis is widespread:

• 30% of all adult cats show signs.
• 60-90% of cats over 12 have radiographic evidence.
• 90% of cats over 15 have at least one affected joint.

Despite these statistics, it is often missed because symptoms develop subtly, and owners may mistakenly attribute changes to "normal aging."

Causes and Risk Factors

• Age: Natural cartilage wear and decreased joint lubrication.
• Genetics: Breeds like Scottish Folds, Maine Coons, and Persians may have predispositions.
• Obesity: Excess weight places immense stress on joints, accelerating damage.
• Previous Injury: Past fractures, ligament tears, or dislocations.
• Conformation & Inactivity: Poor limb alignment and lack of exercise weaken supporting muscles.

Recognizing the Subtle Signs

Cats hide pain instinctively. Watch for these behavioral and physical changes:

Mobility Changes

• Reduced Activity: Sleeping more, less interest in play or climbing.
• Difficulty Jumping: Hesitation, missed jumps, or vocalizing upon landing.
• Stiffness: Especially after rest; a noticeable "warm-up" period.
• Limping: Often subtle and intermittent.

Behavioral & Grooming Shifts

• Litter Box Avoidance: Difficulty entering high-sided boxes.
• Poor Coat Condition: Matted fur (especially on the back) due to reduced grooming.
• Personality Changes: Irritability, hiding, or aggression when touched.
• Altered Sleeping Spots: Seeking softer, more accessible beds over high perches.

Physical Indicators

• Muscle Atrophy: Wasting of thigh or shoulder muscles.
• Joint Swelling or Warmth: Visible enlargement of joints.
• Reduced Flexibility: Trouble grooming hard-to-reach areas.

Diagnostic Process

A proper diagnosis involves a veterinary exam and typically imaging.

Veterinary Examination

• Gait Assessment & Joint Palpation: Checking for pain, swelling, and reduced range of motion.
• Muscle Evaluation: Identifying asymmetry or wasting.

Diagnostic Imaging

Additional Tests

• Blood Work: Rules out other conditions and establishes baseline health before medication ($150-$300).
• Joint Fluid Analysis: Used if inflammatory or infectious arthritis is suspected ($100-$200).

Treatment & Management Strategies

While incurable, arthritis can be effectively managed through a multi-modal approach.

1. Pain Management Medications

NSAIDs (e.g., Meloxicam, Robenacoxib)

• First-line for reducing inflammation and pain.
• Critical: Use only veterinary-prescribed NSAIDs. Human medications are toxic to cats.
• Require regular blood work to monitor kidney and liver function.

Other Medications

• Gabapentin: For chronic neuropathic pain; may cause initial sedation.
• Buprenorphine: Opioid for moderate to severe pain.
• Amantadine: Adjunct medication for chronic pain states.

2. Joint Supplements & Nutraceuticals

• Glucosamine & Chondroitin (Cosequin, Dasuquin): Support cartilage health.
• Omega-3 Fatty Acids (Fish Oil): Powerful natural anti-inflammatories.
• Green-Lipped Mussel (Antinol, Glyde): Provides omega-3s and glycosaminoglycans.
• Polysulfated Glycosaminoglycans (Adequan): Injectable supplement that promotes cartilage repair.

3. Complementary Therapies

• Acupuncture / Cold Laser Therapy: Reduces pain and inflammation, promotes healing.
• Physical Therapy & Hydrotherapy: Builds muscle strength with low-impact exercise.
• Therapeutic Massage & Ultrasound: Improves circulation and reduces muscle tension.

4. Weight Management

This is the single most important modifiable factor. Even a small amount of weight loss can dramatically reduce joint stress and pain.

5. Environmental Modifications

Make your home accessible and comfortable:

• Litter Boxes: Use low-sided or ramped boxes placed on every floor.
• Sleeping Areas: Provide orthopedic or heated beds in warm, draft-free spots.
• Accessibility: Install ramps or pet stairs to favorite furniture and windowsills.
• Flooring: Use non-slip rugs to prevent slipping on hard surfaces.
• Feeding: Raise food/water bowls to a comfortable height.

6. Surgical Options (for severe cases)

• Femoral Head Ostectomy (FHO): Removes the head of the femur to relieve hip pain.
• Arthrodesis (Joint Fusion): Eliminates motion in a severely painful joint.
• Joint Replacement: Rare and costly, but an option for specific joints.

Creating a Long-Term Management Plan

1. Partner with Your Veterinarian: Establish a baseline and schedule regular rechecks (every 3-6 months).
2. Implement Home Care:
   • Monitor Daily: Track mobility, grooming, litter box use, and mood.
   • Encourage Gentle Exercise: Short, frequent play sessions.
   • Provide Warmth: Heated beds or warm compresses can soothe stiff joints.
3. Assess Quality of Life: Regularly evaluate your cat's ability to move, eat, groom, and show interest in their surroundings. Work with your vet to make compassionate decisions if pain cannot be adequately controlled.

Prevention & Early Intervention

• Maintain a Lean Body Weight throughout your cat's life.
• Promote Regular, Appropriate Exercise to maintain muscle strength.
• Provide a Balanced Diet and consider joint supplements for at-risk breeds or seniors.
• Schedule Regular Veterinary Checkups, especially for cats over 7 years old.

Conclusion

Feline arthritis is a highly manageable condition. By learning to recognize its subtle signs and committing to a comprehensive treatment plan—encompassing weight control, medication, supplements, and home modifications—you can ensure your cat enjoys a comfortable, happy, and engaged life in their senior years. Never dismiss changes as "just old age"; proactive veterinary care is the key to effective pain management.
