Can Cats Eat Eggs? Cooked, Raw and Egg Shells Explained
Eggs are a nutritional powerhouse for people, and many cat owners wonder whether their cats can share the benefit. The short answer is yes, in moderation and when cooked. As with many foods, how an egg is prepared matters more than the egg itself.
What eggs offer a cat
An egg contains high-quality protein with an amino acid profile that suits a carnivore, along with fat, vitamins A, D, B12 and riboflavin and minerals such as selenium. The yolk contributes most of the fat and fat-soluble vitamins, while the white is mostly protein.
Even so, eggs do not cover every need of a cat. They do not provide enough taurine, calcium or certain other nutrients to serve as a main diet. Think of cooked egg as a snack or a topper, not a replacement for a complete cat food.
The best way to serve eggs
- Scramble or boil. Cook the egg thoroughly until the white and yolk are firm.
- Use no fat or seasoning. Skip butter, oil, salt, pepper, onions, garlic, cheese and milk. Onion and garlic are toxic, as explained in are onions and garlic toxic to cats.
- Chop finely. Serve a small spoonful, cooled to room temperature.
- Refrigerate leftovers and use them within a day or two.
How much is okay?
A large egg has roughly 70 calories. For a typical cat that needs 200 to 250 calories a day, that is almost a third of daily intake, so a whole egg is too much for a treat. A spoonful of scrambled egg, which might be 10 to 15 calories, is more appropriate. Keep treats to about 10 percent of daily calories in total. Our cat food calculator shows how to work out your cat's daily allowance.
Why raw eggs are a problem
Two issues explain why vets are cautious with raw eggs:
- Salmonella. Raw eggs can carry the bacteria on the shell and inside. Cats are somewhat more resistant than people, but they can still become ill, and they can carry the bacteria without symptoms and spread it around the home.
- Avidin. Raw egg white contains a protein that binds biotin, a B vitamin. Occasional exposure is unlikely to matter, but regular raw egg white can contribute to biotin deficiency, which affects skin and coat.
Cooking destroys avidin and kills Salmonella, which is the simplest way to avoid both problems. Our guide on raw meat for cats covers similar concerns.
Egg allergies and sensitivities
Some cats react to eggs with itching, skin rashes, vomiting or diarrhea. Food allergies are not very common, but if your cat shows signs after eating egg, stop feeding it and talk to your vet. Persistent itching or digestive trouble should be examined, because other problems such as fleas, environmental allergies or gastrointestinal disease can look similar.
What about egg shells?
Egg shells are mostly calcium carbonate. They are not poisonous, but the sharp edges can irritate the mouth and gut, and the calcium is not well balanced for a cat's needs. If your cat needs calcium or any supplement, ask your vet for a product designed for cats rather than guessing.
Eggs for kittens, seniors and sick cats
Kittens need a complete kitten food, and a lick of cooked egg is fine as an occasional treat. Senior cats, particularly those with kidney disease, often need controlled protein and phosphorus, so ask your vet before adding eggs. Cats with pancreatitis or diabetes also need individual dietary advice.

| Question | Answer |
|---|---|
| Safe form | Scrambled or boiled, plain, fully cooked |

| Sensible treat size | One to two teaspoons |
| Frequency | Once or twice a week |
| Avoid | Raw egg, butter, oil, salt, cheese, onion or garlic |
Eggs and a healthy coat
Some owners add egg to improve coat shine, and the fat and protein in a cooked yolk can contribute. A dull coat in a cat that eats a complete diet is more often a sign of an underlying problem, such as obesity, skin disease, parasites or illness, than of a missing egg. If your cat's coat looks poor, see a vet before changing the diet.
Signs your cat did not tolerate it
Soft stool, vomiting, gas or itching after eating egg can mean a sensitivity. Stop feeding it and let your vet know if the signs persist. Reintroduce foods one at a time and in tiny amounts so you can identify the culprit.
Other safe protein treats
If you want variety, plain cooked chicken, turkey and salmon are usually well tolerated. As always, introduce new foods slowly and one at a time.

Frequently asked questions
Can cats eat scrambled eggs?
Yes, if they are plain and fully cooked. Make them without butter, oil, milk or salt, and serve a spoonful at most.
Can cats eat raw eggs?
It is best to avoid them. Raw eggs may carry Salmonella, and raw egg white contains avidin, which can reduce absorption of biotin if fed regularly.
Are egg shells safe for cats?
Shells are not toxic, but they can be sharp and are not a reliable calcium source. Skip them unless your vet recommends a specific supplement.
How many eggs can a cat eat?
A small spoonful of cooked egg once or twice a week is plenty for most cats. A whole egg adds about 70 calories, which is a large share of a small cat's day.
