Cat Feline Immune Polyarthritis Welfare

Immune-mediated polyarthritis causes significant joint pain in cats - recognition, diagnosis, and treatment enable return to comfortable quality of life.

Key Facts

Feline immune-mediated polyarthritis affects multiple joints with pain and swelling
Diagnosis requires joint fluid analysis to distinguish from septic arthritis
Prednisolone is effective first-line treatment with response typically seen within 1-2 weeks
Some cases require additional immunosuppressants if prednisolone alone is insufficient
Monitoring for infection before immunosuppression is critical to avoid worsening septic arthritis

Welfare Considerations

Immune polyarthritis causes significant, often severe joint pain that dramatically impairs cat welfare and mobility. Prompt diagnosis and appropriate immunosuppressive treatment enables return to comfortable, pain-free movement for the majority of affected cats.

What You Can Do

Seek veterinary assessment for cats showing reluctance to jump, stiff gait, or joint swelling
Ensure joint fluid analysis is performed to confirm immune-mediated rather than septic cause
Monitor treated cats regularly for treatment response and side effect management
