Safe to share · Cats · full breakdown on the linked food page
Safe cooked (no salt/butter). Eggs are a great protein source. Raw egg whites carry a salmonella and biotin risk.
Short answer
Yes, fully cooked plain egg is a safe and excellent source of protein for cats. Ensure it's cooked thoroughly with no added salt, butter, oil, or seasonings. Start with just a teaspoon-sized amount to see how your cat tolerates it. Remember that raw egg whites carry a risk of salmonella and can interfere with biotin absorption, so always cook eggs fully before offering. This should be a small supplement to their regular balanced diet, not a meal replacement.
