Feline pemphigus foliaceus causes crusting, pustule formation, and systemic signs. Long-term immunosuppressive management is required for welfare-positive outcomes.
Pemphigus foliaceus in cats causes significant welfare harm through painful skin lesions and systemic illness. The characteristic crusting on the face and ears is often misidentified as ringworm or seborrhea, delaying welfare-improving diagnosis. When foot pads are affected, the pain causes reluctance to walk, altered gait, and avoidance of normal surface contact. Generalized disease causes fever, lethargy, and systemic malaise reflecting the immune dysregulation underlying the condition.
The long-term welfare management of feline pemphigus requires balancing disease control against immunosuppressive drug side effects. Prednisolone side effects — polyuria, polydipsia, muscle wasting, weight gain, and increased infection risk — require monitoring and minimum effective dose management. Regular clinical assessment including disease activity scoring and side effect monitoring maintains optimal welfare throughout the chronic disease course.
