Understanding Osteoarthritis in Cats

What is Osteoarthritis (Degenerative Joint Disease – DJD)?

Osteoarthritis (OA) is a chronic, progressive condition where the protective cartilage inside joints deteriorates, leading to:

• Pain & stiffness due to inflammation and cartilage damage.

• Bone remodeling as the body attempts to stabilize the affected joint.

• Loss of mobility that worsens over time.

Unlike dogs, cats with OA often do not limp but display subtle changes in behavior. Studies show that 90% of cats over 10 years old have some form of arthritis, making it one of the most underdiagnosed conditions in feline medicine.

Signs of Osteoarthritis in Cats

OA in cats is underdiagnosed because symptoms are often subtle. Common behavioral and physical changes include:

• Reluctance to jump onto furniture or climb stairs.

• Increased sleeping or reduced activity.

• Difficulty using the litter box, especially with high sides.

• Irritability or aggression when touched.

• Stiffness after resting or difficulty moving.

• Reduced grooming, leading to a matted coat.

Many cat owners mistakenly believe these signs are just "normal aging," but they often indicate chronic pain and joint disease.

How is Osteoarthritis Diagnosed?

A veterinary examination, combined with X-rays or advanced imaging, helps confirm OA by detecting:

• Joint space narrowing.

• Bone spurs (osteophytes).

• Cartilage loss and inflammation.

Your veterinarian may also use mobility scoring systems and pain assessment tools to evaluate the extent of arthritis.

Treatment Options for Osteoarthritis in Cats

Although OA is not curable, several treatment strategies help slow progression and improve quality of life.

Pain Management & Anti-Inflammatory Therapy

• Solensia™ (frunevetmab) – A new monoclonal antibody therapy specifically for cats that provides long-term pain relief.

• NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) – Must be used cautiously in cats under veterinary supervision.

• Steroid injections for severe cases that do not respond to other treatments.

Joint Supplements & Nutraceuticals

• Omega-3 fatty acids – Reduce joint inflammation.

• Glucosamine & chondroitin – Support cartilage health and joint lubrication.

• Adequan® (polysulfated glycosaminoglycan) – Helps prevent cartilage breakdown and supports joint function.

Weight Management & Mobility Support

• Obesity worsens OA – A low-calorie, joint-friendly diet helps maintain ideal weight.

• Raised food and water bowls reduce joint strain.

• Soft, orthopedic bedding improves comfort.

Environmental Modifications for Arthritic Cats

"An often-overlooked yet very important environmental modification is slip-free flooring."

• Provide ramps or steps to access favorite perches.

• Use non-slip rugs to prevent slipping.

• Lower litter box entry for easier access.

Physical Therapy & Alternative Treatments

For cats with chronic OA, multimodal management is essential. Additional therapies include:

• Acupuncture & chiropractic care – Help alleviate pain and improve mobility.

• Laser therapy – Reduces inflammation and enhances tissue healing.

• Rehabilitation exercises – Maintain muscle strength and joint flexibility.
