Yes, cats can eat eggs — but only when they are fully cooked and served plain. Eggs are a good source of protein and essential amino acids for cats, making them a healthy occasional treat.
Are eggs safe for cats?
Fully cooked eggs are safe for most cats. Eggs provide high-quality animal protein, which aligns well with a cat’s nutritional needs as obligate carnivores. They also contain taurine, an essential amino acid that cats cannot produce on their own.
According to the ASPCA, plain cooked eggs are not toxic to cats and can be offered as an occasional treat. The key word is “plain” — eggs cooked with oil, butter, salt, or seasonings can cause digestive issues or more serious health problems.
Raw eggs vs cooked eggs: which is safer?
Cooked eggs are the safer choice. Raw eggs carry two main risks:
- Salmonella risk — raw eggs can contain salmonella bacteria, which can cause food poisoning in both cats and humans
- Biotin deficiency — raw egg whites contain avidin, a protein that interferes with biotin absorption. Cooking destroys avidin, making the egg white safe to eat
Boiled, poached, or scrambled eggs without any added fat or seasoning are all safe preparation methods. Make sure the egg is cooked through — no runny yolks.
How much egg can a cat eat?
A serving of egg should be no more than one tablespoon of cooked egg for an average-sized cat. This is roughly one-quarter of a large egg. Offer egg as an occasional treat — once a week is plenty.
One large egg contains about 70 calories, and a full egg would represent roughly one-third of a cat’s daily caloric needs. This is why small portions matter. Treats should make up no more than 10% of your cat’s daily calorie intake, according to veterinary nutrition guidelines.
Nutritional benefits of eggs for cats
Eggs offer several nutritional benefits when fed appropriately:
- High-quality protein — eggs contain all essential amino acids cats need
- Taurine — essential for heart and eye health in cats
- Vitamin B12 — supports nerve function and energy metabolism
- Selenium — an antioxidant that supports immune function
- Healthy fats — provide energy and support coat health
Can kittens eat eggs?
Kittens can eat small amounts of cooked egg, but their primary nutrition should come from a complete and balanced kitten food. If you offer egg to a kitten, start with a tiny amount — about half a teaspoon — and watch for any digestive issues. Kittens have sensitive stomachs and may not tolerate new foods as well as adult cats.
Signs of egg allergy or intolerance in cats
While uncommon, some cats may be allergic or intolerant to eggs. Watch for these symptoms after feeding:
- Vomiting or diarrhea
- Itchy skin or excessive scratching
- Ear inflammation
- Hair loss in patches
If you notice any of these signs, stop feeding eggs and consult your veterinarian. Most cats tolerate eggs well, but individual reactions vary.
Frequently asked questions about cats and eggs
Can cats eat scrambled eggs?
Yes, as long as they are cooked without butter, oil, milk, or seasoning. Plain scrambled eggs are safe for cats in small amounts.
Can cats eat eggshells?
Eggshells are not recommended. They pose a choking hazard and the sharp edges could irritate your cat’s digestive tract. If you want to add calcium to your cat’s diet, ask your veterinarian for a safer option.
Can cats eat egg whites only?
Yes, but only cooked. Raw egg whites contain avidin, which can interfere with biotin absorption. Cooked egg whites are safe and provide protein without the fat found in yolks.
Can cats eat eggs every day?
Daily feeding is not recommended. Eggs should be an occasional treat — once a week is sufficient. A balanced commercial cat food provides all the nutrients your cat needs.
Are eggs a good source of taurine for cats?
Yes, eggs contain taurine, which is essential for cats. However, commercial cat foods are already supplemented with taurine, so eggs are an extra source rather than a necessary one.
Bottom line
Cooked plain eggs are a safe, nutritious treat for most cats when offered in moderation. Stick to small portions — about one tablespoon of cooked egg per serving — and avoid raw eggs, seasonings, and cooking fats. As with any new food, introduce eggs gradually and watch for signs of digestive upset.
