Plain, fully cooked eggs are generally safe for most cats as an occasional treat.¹ Avoid raw or undercooked eggs, and contact your veterinarian if your cat ate egg with onions or garlic or develops vomiting or diarrhea.²,⁵,⁸,⁹
Cooked egg is listed among foods that are safe and often enjoyed by cats, as long as it is offered without seasonings.¹ Raw eggs are higher risk because they can contain foodborne bacteria, and raw egg whites contain avidin which can reduce biotin absorption when fed repeatedly.²,⁴,⁵ Keep egg as an occasional treat so it stays within the recommended treat allowance, generally less than 10% of daily calories.⁶,⁷
What to do if your cat ate eggs?
Check what your cat ate: cooked vs. raw, roughly how much, and whether it was seasoned or mixed with other foods.
If it was plain cooked egg and your cat is acting normal, offer fresh water and monitor for vomiting, diarrhea, reduced appetite, or lethargy over the next 24 hours.⁸
If it was raw or undercooked egg, call your veterinarian for guidance, especially for kittens, seniors, or cats with chronic illness.²,⁴
If the egg contained onions, garlic, chives, or seasoning blends, contact a veterinarian right away because Allium ingredients can be dangerous to cats.⁹
Seek urgent veterinary care if you see repeated vomiting, bloody diarrhea, marked weakness, trouble breathing, collapse, or pale gums.⁸,⁹
