Can Cats Eat Eggs? NZ Safety Answer
Can cats eat eggs in NZ? Yes, plain cooked eggs are safe in small amounts. Avoid raw eggs due to Salmonella and biotin deficiency risks.
Quick answer
Plain cooked egg only as a tiny occasional treat; avoid raw egg. VCA's raw food guidance for cats highlights bacterial and balance risks.
Why
Cooked eggs can be a highly nutritious, protein-rich treat for cats, offering amino acids, vitamins, and minerals. However, they must be prepared and fed correctly. Raw eggs present significant food safety risks. They can carry harmful bacteria like *Salmonella* and *E. coli*, which can cause severe food poisoning in cats (manifesting as vomiting, diarrhea, and fever) and pose a contamination risk to humans in the household. Furthermore, raw egg whites contain avidin, a protein that binds to biotin (Vitamin B7) and prevents its absorption. Over time, this can lead to a biotin deficiency, resulting in skin and coat problems. Cooking destroys avidin and kills bacteria, making cooked eggs safe. However, human preparations of eggs—scrambled with butter, milk, salt, cheese, or seasoned with garlic and onions—are highly unsuitable for cats.
How much is a problem
Eggs should only be fed in moderation as an occasional treat, not a meal replacement. A single teaspoon of plain, scrambled or boiled egg is a safe portion. Too much egg can cause digestive upset or contribute to weight gain, as eggs are relatively calorie-dense for a small animal like a cat.
If your cat has eaten it
If your cat ate plain, fully cooked egg, they should be fine. If they ate raw egg, monitor them closely over the next 24 to 72 hours for symptoms of bacterial food poisoning, including vomiting, diarrhea, fever, and lethargy.
Safer alternatives
Use commercial cat treats or small pieces of plain cooked chicken or fish.
