Can Cats Eat Eggs? Cooked vs. Raw, and How Much Is Safe
Yes — cats can eat eggs, and in the right form, they're actually a genuinely nutritious occasional treat. The key distinction that matters most is cooked versus raw: fully cooked eggs are a safe, protein-rich snack, while raw eggs carry real risks that make them worth avoiding.
This article is for general information only and isn't a substitute for veterinary care. If your cat has an existing health condition, check with your vet before adding eggs to their diet.
The Short Version
- Cooked eggs (scrambled, boiled, or hard-boiled): Safe in moderation — both the yolk and white
- Raw eggs: Not recommended — risk of bacteria and a nutrient-absorption issue explained below
- Portion: About 1-2 teaspoons of plain cooked egg, a few times a week, is plenty for most adult cats
- Always plain: No salt, butter, oil, or seasoning of any kind
Why Cooked Eggs Are a Good Occasional Treat
Eggs are packed with high-quality protein, amino acids, and fatty acids, and they're highly digestible — a good fit for a species that's an obligate carnivore. In moderation, cooked eggs can support muscle maintenance and contribute to a shiny coat and healthy skin.
Why Raw Eggs Are a Different Story
Bacterial risk — Raw eggs can carry Salmonella or E. coli, which can make a cat (and the humans in the household) sick. Symptoms in cats can include vomiting, diarrhea, fever, or lethargy — though notably, some infected cats show few or no obvious symptoms while still being able to spread bacteria through their saliva or stool.
Biotin absorption issue — Raw egg whites contain a protein called avidin, which binds to biotin (vitamin B7) and prevents your cat's body from absorbing it properly. Over time, this can contribute to a biotin deficiency, which can affect skin and coat health. Cooking the egg deactivates avidin and removes this concern entirely.
Kittens and immunocompromised cats are at higher risk — Young kittens, senior cats, and cats with conditions like FIV or FeLV have less capacity to fight off a bacterial infection, so raw egg exposure is riskier for them specifically.
Given these risks are entirely avoidable simply by cooking the egg, there's little reason to feed eggs raw when the cooked version offers the same nutritional benefits more safely.
How to Prepare Eggs for Your Cat
- Cook the egg fully — scrambled, boiled, or hard-boiled all work well
- Keep it completely plain — no salt, pepper, butter, oil, milk, or seasoning
- Let it cool before serving
- Offer a small amount (a teaspoon or two) rather than a whole egg at once
- Remove the shell entirely before serving
How Much Is Too Much?
As with any treat, eggs should stay within the general guideline of treats making up no more than about 10% of your cat's total daily calories, with the remaining 90% coming from a complete and balanced cat food. A teaspoon or two of cooked egg a few times a week is a reasonable amount for most healthy adult cats — it isn't something to make a daily staple.
Can Kittens Eat Eggs?
Yes, cooked eggs in small amounts are generally fine for kittens too, but eggs shouldn't be a substitute for a complete kitten formula, since growing kittens have specific nutritional needs that eggs alone won't meet. Check with your vet before introducing eggs to a kitten's diet.
When to Call Your Vet
Contact your vet if your cat eats raw egg (accidentally or otherwise) and shows any of these signs:
- Vomiting or diarrhea
- Lethargy
- Fever
- Loss of appetite
Frequently Asked Questions
Is the egg yolk or the egg white better for cats? Both are fine once cooked. The yolk tends to be the more nutrient-dense part, but the biotin-binding concern in raw form applies specifically to the egg white — another reason cooking the whole egg is the simplest, safest approach.
Will my cat actually like eggs? That depends entirely on your individual cat — some cats enjoy them, others show no interest at all. There's no harm in offering a small taste to see how your cat responds.
Can eggs replace part of my cat's regular food? No. Eggs should stay an occasional treat, not a dietary staple or replacement for a complete and balanced cat food, which is formulated to meet all of your cat's nutritional needs.
