Can Cats Eat Eggs? Safe Ways to Feed Them
Start here
Yes — cats can eat eggs, as long as they're fully cooked and plain. Cooked eggs are a good source of protein and amino acids for cats, who are meat-eaters by nature. The key rules: cook them thoroughly (scrambled or boiled with no butter, oil, salt or seasoning), and keep them to an occasional treat rather than a meal. Raw eggs carry real risks and should be avoided.
Are eggs good for cats?
Cats are obligate carnivores, meaning their bodies are designed to run on animal protein — and eggs are an excellent, highly digestible protein source. A little cooked egg delivers quality amino acids plus nutrients like vitamin B12 and riboflavin.
That said, eggs are a treat, not a complete diet. They don't contain everything a cat needs (notably taurine in the amounts a cat requires), so they should complement a balanced commercial cat food, not replace it. Think of eggs as an occasional bonus, not a daily staple.
Why raw eggs are risky
Feeding raw egg to a cat carries two specific problems:
- Salmonella and E. coli: raw eggs can carry bacteria that cause vomiting, diarrhea and food poisoning in cats — and can spread to people in the household.
- Avidin and biotin: raw egg white contains a protein called avidin that binds biotin (a B vitamin). Over time, lots of raw white can contribute to a biotin deficiency, affecting skin and coat.
Cooking solves both issues: heat kills the bacteria and deactivates the avidin. So cooked egg gives you the benefits without the downsides.
How to serve eggs safely
Keep it simple and plain:
| Do | Don't |
|---|---|
| Scramble or hard-boil until fully cooked | Serve raw or runny |
| Cook with no oil, butter or spray | Add salt, pepper or seasoning |
| Offer a small piece, cooled | Add onion, garlic or chives (toxic to cats) |
| Chop into bite-sized bits | Feed a whole egg as a meal |
Practical take: A teaspoon or two of plain cooked egg is plenty for an average cat, offered once or twice a week at most.
Portion size and calories
Eggs are calorie-dense, and cats are small. All treats combined — eggs included — should stay under about 10% of your cat's daily calories. For most cats a small spoonful of cooked egg is a full portion; a whole egg is far too much and can lead to weight gain if it becomes a habit.
Watch for signs a treat didn't agree with your cat: vomiting, diarrhea, or a loss of appetite. And because eggs are a common food allergen, introduce them in a tiny amount the first time and see how your cat responds before offering more.
Track new treats the smart way
Whenever you add a new food like egg, it's worth noting the first time your cat tries it and whether anything changed afterward — a bout of loose stool, itchy skin, or no reaction at all. Keeping a simple log of new foods and how your cat responded makes it far easier to tell a true food sensitivity from a one-off, and gives your vet real information if a diet question ever comes up.

Frequently asked questions
Can cats eat scrambled eggs?
Yes, scrambled eggs are one of the safest ways to feed egg to a cat — as long as they're cooked plain with no butter, oil, salt or seasoning. Serve a small amount, cooled, as an occasional treat rather than a meal.
Can cats eat raw eggs?
No, raw eggs are not recommended. They can carry Salmonella and E. coli, and raw egg white contains avidin, a protein that can interfere with biotin absorption over time. Cooking the egg fully removes both risks.
How much egg can I give my cat?
A small amount — a teaspoon or two of cooked egg — is plenty for an average cat, offered once or twice a week at most. All treats together should stay under about 10% of your cat's daily calories to avoid weight gain.
Can cats eat eggshells?
Some owners grind eggshell as a calcium supplement, but you should only do this with your vet's guidance, since a balanced cat food already provides the calcium your cat needs. Whole or large shell pieces can be a choking or digestive hazard, so don't offer them casually.
Can kittens eat eggs?
A tiny amount of plain cooked egg is generally fine for kittens as an occasional treat, but their main nutrition should come from a complete kitten food formulated for growth. Check with your vet before adding any extras to a kitten's diet.
