Why eggs are good for cats
Eggs are a complete protein, meaning they contain all the essential amino acids cats require, in a form that is easy to digest. That makes them a helpful protein boost for older cats who may be losing muscle or who have become finicky. Eggs also supply vitamins and healthy fats, and most cats find them tasty enough to tempt a flagging appetite.
Cooked only, always
Raw eggs bring two problems. Raw egg whites contain avidin, which binds biotin and can lead to a deficiency over time, and raw eggs can carry Salmonella. Cooking eliminates both risks. Scramble or hard-boil the egg with nothing added, let it cool, and serve a small portion. Keep it plain, since the butter, oil, salt, onion, or garlic in human egg dishes can harm cats.
How much egg to feed
Treats should make up no more than about 10 percent of daily calories, and eggs are calorie-dense. A tablespoon of cooked egg once or twice a week is a sensible amount. Older cats put on weight easily when they slow down, so resist making egg a daily habit. It is a supplement, not a meal.
A senior-cat note
For an aging cat that picks at food, a little warm scrambled egg can spark interest and add gentle protein. Watch for any sign of sensitivity, such as itchy skin or loose stool, especially in cats with a history of food allergies. If your senior is losing weight or refusing meals, see your vet rather than relying on eggs to fill the gap, since appetite changes often signal treatable disease.
The bottom line
Plain cooked eggs are a safe, protein-rich occasional treat for most cats. Keep portions small, preparation simple, and the core of the diet a complete senior food. Used this way, eggs are a wholesome way to add variety to your older cat's menu.

Frequently Asked Questions
How should I cook eggs for my cat?
Cook them plainly and fully: scrambled or boiled with no butter, oil, salt, milk, onion, or garlic. Let the egg cool and offer a small amount. Fully cooked eggs are safe and easy to digest, while raw eggs are not. Onion and garlic, common in omelets, are toxic to cats, so share only plain egg you cooked specifically for your cat without any seasoning.
Can cats eat raw eggs?
No. Raw egg whites contain avidin, which interferes with absorption of biotin, an important B vitamin, and raw eggs can carry Salmonella. Senior cats with weaker immune systems are especially vulnerable to foodborne illness. Cooking solves both problems: it neutralizes avidin and kills bacteria. Always cook eggs fully before offering any to your cat, and never give raw egg as a coat supplement.
How much egg can a senior cat have?
A small amount, such as a tablespoon of cooked egg or a portion of one egg, once or twice a week, is plenty. Eggs are calorie-dense and should stay within the 10 percent of daily calories reserved for treats. Older, less active cats gain weight easily, so keep portions modest. Eggs are a supplement to a balanced diet, never a replacement for complete cat food.
Are eggs good for senior cats?
Yes, in moderation. Eggs are a complete protein with all the essential amino acids cats need, plus easy-to-digest nutrients that suit aging cats who may be losing muscle. They can be a tempting topper for a picky senior. Eggs are not a complete diet, though, since they lack the right calcium balance and other nutrients, so they work best as an occasional protein boost on top of regular food.
Can cats be allergic to eggs?
Yes, although it is uncommon. Eggs are among the proteins that can trigger food sensitivities in cats, which may show up as itchy skin, ear issues, or digestive upset. Introduce egg in a tiny amount the first time and watch for any reaction over a day or two. If your senior cat has a history of food sensitivities or chronic GI issues, check with your vet before adding egg.
Can cats eat eggshells?
Finely ground eggshell is sometimes used as a calcium source in homemade diets, but it must be done correctly to balance calcium and phosphorus, which is easy to get wrong. For most owners feeding a complete commercial diet, eggshells are unnecessary and add no benefit. If you are building a homemade diet for a senior cat, work with your vet or a veterinary nutritionist rather than adding eggshell on your own.
