Eosinophilic Granuloma Complex in Cats: Welfare

Feline eosinophilic granuloma complex causes painful skin lesions driven by allergic hypersensitivity, requiring identification and management of underlying triggers.

Key Facts

Eosinophilic granuloma complex (EGC) includes indolent ulcers, eosinophilic plaques, and granulomas
Indolent ulcers typically affect the upper lip and are painless; eosinophilic plaques are intensely pruritic
Flea allergy, food allergy, and environmental allergy are the most common underlying triggers
Corticosteroids provide rapid symptomatic relief but do not address the underlying allergen
Allergen identification through elimination diets or intradermal testing is necessary for long-term control

Welfare Considerations

Cats with eosinophilic plaques experience intense pruritus causing self-trauma that compounds the primary lesion. The cycle of scratching, secondary infection, and lesion expansion is distressing. Many cats receive recurrent steroid injections that control signs but allow continued allergen exposure rather than addressing the cause. Welfare-positive management identifies and eliminates the underlying allergen - most commonly fleas or dietary protein - removing the stimulus rather than suppressing the immune response repeatedly.

What You Can Do

Ensure rigorous flea control for all pets in the household as a first step
Pursue strict elimination dietary trials using novel protein or hydrolyzed diets for 8-10 weeks
Ask your vet about allergy testing as an alternative to long-term steroid management
Monitor for steroid side effects including weight gain and diabetes with regular bloodwork
