Raw eggs
Raw eggs / Raw egg whites
Raw whole eggs and raw egg whites are not acutely toxic to cats, but they carry specific risks that make them inappropriate as regular food. Cooked eggs are a safe, nutritious treat; raw eggs are not recommended due to bacterial contamination and a vitamin-binding protein that interferes with nutrient absorption.
Important Notes
Bacterial risk: raw eggs may contain Salmonella or Listeria — causes vomiting, diarrhea, lethargy, and in severe cases, life-threatening sepsis
Avidin risk: raw egg whites contain avidin, a protein that binds biotin (vitamin B7) and prevents its absorption; regular feeding causes biotin deficiency — dry skin, hair loss, neurological issues
Cooked eggs: safe, nutritious, and avidin is deactivated by cooking; plain scrambled or boiled egg is an acceptable occasional treat
A single accidental bite of raw egg is unlikely to cause harm; regular feeding of raw eggs or egg whites is the concern
If your cat regularly eats raw eggs and shows skin or neurological symptoms, consult your vet
