Yes — safe in moderation
Yes — fully cooked eggs are a safe, protein-dense treat for cats. Scrambled or boiled plain, in small portions. Raw eggs are off the menu.
Eggs are sometimes called “nature’s multivitamin” and for obligate carnivores like cats they’re a biologically appropriate treat: complete amino acids, B vitamins, selenium. Cooked thoroughly, they suit most cats including seniors. Raw egg carries salmonella risk and raw white contains avidin, which blocks biotin uptake over time. Egg should remain a treat — a whole egg is a third of a cat’s daily calories, so think in teaspoons, not omelettes.
A teaspoon or two of plain scrambled/chopped boiled egg, a couple of times a week. No salt, butter, milk, onion or chives in the pan (onion and chives are toxic to cats). Egg works well as an appetite-encourager for picky or recovering cats — ask your vet first if your cat is unwell.
Plain cooked chicken remains the gold-standard human-food treat for cats.
