Myasthenia Gravis in Cats: Welfare and Management

Feline myasthenia gravis is a neuromuscular disorder causing progressive weakness. This guide covers recognition, welfare impacts, and management strategies.

Key Facts

Myasthenia gravis disrupts the neuromuscular junction causing muscle weakness
Signs include generalised weakness, exercise intolerance, and megaoesophagus
Regurgitation from megaoesophagus is a major welfare and health concern
Aspiration pneumonia is a serious and life-threatening complication
Both congenital and acquired forms exist in cats
Treatment with pyridostigmine can improve muscle function significantly

Welfare Considerations and Management

Management of feline myasthenia gravis requires addressing both the neuromuscular dysfunction and its complications. Feeding from elevated positions reduces regurgitation risk. Pyridostigmine improves neuromuscular transmission. Immunosuppression may be needed for acquired forms. Welfare monitoring focuses on nutritional status, respiratory health, and quality of life assessment.

What You Can Do

Feed from elevated positions to reduce megaoesophagus complications
Monitor for signs of aspiration pneumonia (coughing, laboured breathing)
Regular reassessment of treatment response and quality of life
Some cats achieve spontaneous remission with appropriate management
