Can Cats Eat Eggs? Safety, Benefits and How to Serve Them

Reviewed by Dr. Ameer Hamza, DVM

Eggs are one of the most nutritionally complete animal foods available — high-quality protein, essential amino acids including taurine, beneficial fats, and a range of vitamins and minerals. For cats, who are obligate carnivores requiring animal protein, cooked eggs are a genuinely beneficial occasional food. The key word is cooked: raw eggs carry significant risks that cooked eggs do not. This guide covers the benefits, the risks, how much to give, and how to prepare eggs for your cat safely.

Are Eggs Safe for Cats?

Cooked eggs are safe for most cats. Eggs are species-appropriate food for obligate carnivores — high in animal protein, containing all the essential amino acids including taurine (which cats cannot synthesise and must consume in diet), and providing vitamins A, D, B12, and riboflavin. They are a dense, highly digestible protein source that most cats find palatable. The safety condition is that they must be plain and cooked — no additions of salt, butter, oil, seasonings, or dairy.

Why Raw Eggs Are Not Safe

Raw eggs carry two distinct risks. Bacterial contamination: Raw eggs may contain Salmonella and Campylobacter. Infection can cause vomiting, diarrhoea, fever, and lethargy in cats. These bacteria can also be transferred from the cat's mouth or faeces to humans in the household, posing a public health risk. Avidin in raw egg white: Raw egg whites contain avidin, a glycoprotein that binds biotin (vitamin B7) in the digestive tract and prevents its absorption. Regular feeding of raw egg whites leads to biotin deficiency, manifesting as poor coat quality, flaky skin, and in severe cases neurological signs. Cooking egg white completely deactivates avidin, eliminating this risk — there is no safety advantage to raw eggs over cooked eggs.

How to Prepare Eggs for Cats

Boiled: Hard-boiled or soft-boiled with no shell fragments — the simplest and cleanest method. Allow to cool and offer a small piece. Scrambled (plain): Egg scrambled in a non-stick pan without oil, butter, salt, or milk. Cool completely before serving. Poached: Plain poached egg with no added water seasonings. What to avoid: Fried eggs (excess fat), eggs with salt or seasoning, eggs cooked with onion or garlic (toxic to cats), or eggs prepared with dairy. Never feed raw egg in any form.

How Much Egg to Give

Treat eggs as an occasional supplement, not a regular meal component. A teaspoon of cooked egg once to three times a week is appropriate for most adult cats. A whole egg contains approximately 70 calories — significant for a cat whose total daily caloric need is around 200–250 kcal. All treats should comprise no more than 10% of total daily calories to avoid unbalancing the nutritionally complete main diet. Eggs are nutritious but not a complete diet for cats — they should supplement, not replace, a complete commercial cat food.

Frequently Asked Questions

Can cats eat eggs safely?

Yes — cooked eggs are safe and nutritious. High in quality animal protein, taurine, vitamins, and fats. Must be plain and fully cooked; raw eggs carry bacterial and avidin risks.

Why are raw eggs unsafe?

Risk of Salmonella/Campylobacter, and raw egg white contains avidin which blocks biotin absorption. Cooking eliminates both risks with no nutritional downside.

How much egg should I give my cat?

One teaspoon of cooked egg, one to three times per week as a treat. Keep all treats under 10% of daily calories.

Can cats eat scrambled eggs?

Yes — plain scrambled egg cooked without butter, oil, salt, or milk is safe. Avoid sharing human-preparation scrambled eggs which typically contain additives.

Are egg yolks or whites better?

Both are safe when cooked. Whites are lower in fat; yolks are richer in fat-soluble vitamins. A whole cooked egg provides the full benefit of both.
