Cat Inflammatory Joint Disease Welfare

Immune-mediated polyarthritis causes painful joint inflammation in cats, requiring accurate diagnosis and appropriate treatment to restore quality of life.

Key Facts

Immune-mediated polyarthritis causes fever, shifting lameness, and reluctance to move
Multiple joints are typically affected simultaneously, distinguishing it from osteoarthritis
Underlying infections, neoplasia, and idiopathic disease are causes requiring investigation
Prednisolone achieves remission in many idiopathic cases
NSAIDs should be avoided as they can exacerbate immune-mediated conditions

Welfare Considerations

Immune-mediated polyarthritis causes significant pain affecting multiple joints simultaneously. The welfare cost of untreated or incorrectly treated polyarthritis is high. Accurate diagnosis distinguishing immune-mediated from infectious or osteoarthritic causes is essential to guide appropriate treatment and restore quality of life.

What You Can Do

Seek specialist assessment for cats with acute-onset shifting lameness and fever
Ensure complete diagnostic workup before starting immunosuppressive treatment
Monitor treatment response carefully and adjust based on clinical signs
