Can Cats Eat Eggs? Scrambled, Boiled and Raw Eggs Explained by a Vet (With Portion Chart)

Are eggs good for cats?

Eggs are good for cats as an occasional treat because they are a complete animal protein, providing every essential amino acid along with vitamin A, vitamin B12, riboflavin and selenium. They are not a meal replacement: eggs alone do not provide the balanced nutrition a complete cat food does.

Those numbers explain the real risk with eggs: not toxicity, but calories. A whole egg is roughly a third of what a 10 lb spayed or neutered cat needs in an entire day.

How much egg can a cat eat?

A cat can eat up to about a quarter to a third of a large cooked egg (12 to 15 g) on a treat day, because treats should stay under 10% of daily calories, and a few times a week is plenty. If your cat also gets other treats that day, cut the egg portion down.

Daily calories in the chart and calculator use the NRC energy formula that the WSAVA uses in its cat treat chart, with treats capped at 10% of the day. Overweight cats, kittens and cats with health conditions need less; see the full food checker to adjust for life stage and health.

Can cats eat scrambled eggs?

Yes, cats can eat scrambled eggs if they are cooked until fully set with no butter, oil, milk, cheese, salt or pepper. The eggs themselves are fine; the extras people add are the problem.

• Scrambled eggs with cheese: skip the cheese. It adds fat, salt and lactose.
• Scrambled eggs with milk: skip the milk. Many adult cats do not digest lactose well.
• Scrambled eggs cooked in butter: a lick will not hurt, but butter is almost pure fat; use a non-stick pan with no fat instead.
• Your leftover breakfast eggs: usually not suitable, because they are often salted or cooked with onion, garlic or chives, which are toxic to cats.

Can cats eat boiled or hard-boiled eggs?

Yes, hard-boiled eggs are the easiest and safest way to give a cat egg, as long as the shell is removed and the egg is chopped into small pieces. Soft-boiled eggs with a runny yolk are not recommended, because the yolk is undercooked.

Cook the egg until both the white and the yolk are firm, cool it, peel it and chop a thumb-tip-sized amount. A whole hard-boiled egg is too big for one cat in one day; refrigerate the rest for your own snack.

Can cats eat raw eggs?

No, cats should not eat raw eggs, because raw eggs can carry Salmonella and E. coli, and raw egg white contains avidin, a protein that blocks the absorption of biotin (vitamin B7). Cooking solves both problems.

• Bacteria: Salmonella can make cats sick, and cats that carry it can pass it to the people in the home.
• Biotin: a deficiency is unlikely from an occasional bite, but regular raw egg white can cause skin and coat problems over time.
• Raw animal foods and bird flu: since 2024 the FDA has linked H5N1 bird flu cases in US cats to raw pet food and raw milk, which is one more reason to keep a cat’s eggs and meat cooked.

Raw yolks carry the same bacteria risk, so “can cats eat raw egg yolk” gets the same answer: no.

Can cats eat egg yolk or egg white?

Cats can eat both cooked egg yolk and cooked egg white: the white is a lean, low-calorie protein, while the yolk carries most of the fat, calories and vitamins. For overweight cats, cooked egg white alone is the lighter choice.

Can kittens eat eggs?

Kittens can have a tiny taste of fully cooked egg once they are weaned and eating kitten food well, but kitten food should supply their nutrition. Growing kittens are more sensitive to stomach upset, and their small calorie budget fills quickly.

Start with a fingertip-sized piece of hard-boiled egg and watch for loose stools over the next day. Never give kittens raw egg.

Can cats eat fried, quail, duck or deviled eggs?

Cats can eat a little plain cooked quail or duck egg, and a fried egg only if it is fully cooked with no oil or butter, but deviled eggs are not suitable because the filling contains mayonnaise, mustard and seasonings. Eggshells should be removed.

• Fried eggs: runny yolks and cooking fat make them a poor choice; a firm, dry-fried egg in a non-stick pan is fine.
• Quail eggs: safe cooked; one quail egg is about a fifth the size of a chicken egg, so it suits a cat’s small portion well.
• Duck eggs: safe cooked, but larger and richer than chicken eggs.
• Deviled eggs: do not share; seasonings can include onion or garlic powder.
• Eggshells: sharp pieces can irritate the mouth and gut; cats on complete cat food do not need extra calcium.

Which cats should not eat eggs?

Cats with egg allergies, kidney disease, pancreatitis or obesity, and cats on a prescription diet, should not get eggs unless their vet agrees. Egg is a less common food allergen in cats than beef, fish or chicken, but it does happen.

• Food allergy: itching, over-grooming, ear problems, vomiting or diarrhea after eating egg.
• Kidney disease: egg yolks add phosphorus and protein that may not fit a kidney diet.
• Pancreatitis or obesity: the fat in yolks can be a problem; cooked white is lighter.
• Prescription diets: any extra food can undo a diet trial, so ask first.

What if my cat ate too much egg or raw egg?

If your cat ate a large amount of cooked egg, expect at most some vomiting or soft stools within a day; if it ate raw egg, watch for vomiting, diarrhea, fever or lethargy over the next few days and call your vet if they appear. One small lick of raw egg rarely causes problems, but kittens, seniors and sick cats are more vulnerable.

• Cooked egg, large amount: skip treats for a day, keep fresh water out and watch the litter box.
• Raw egg: wipe the bowl and area, wash your hands, and monitor for 3 to 5 days.
• Egg with onion, garlic or chives: call your vet; these damage red blood cells.

How do you cook eggs for cats?

To cook eggs for a cat, hard-boil or dry-scramble them until the white and yolk are completely firm, use no fat, salt or seasoning, cool them, then chop a small portion and refrigerate the rest. The FDA advises cooking eggs until both the yolk and white are firm.

1. Hard-boil: cover the egg with water, bring to a boil, simmer about 10 to 12 minutes, then cool in cold water.
2. Or dry-scramble: whisk the egg with nothing added and cook in a non-stick pan, stirring, until no wet egg remains.
3. Cool and portion: chop the egg small and weigh or eyeball your cat’s portion from the chart.
4. Serve: on its own as a treat, or sprinkled over the usual meal.
5. Store: refrigerate leftovers and use within a few days.

Is egg in cat food good?

Egg in a complete cat food is a good-quality protein, and because the recipe is balanced, it is a safer way to give your cat egg every day than feeding egg from your kitchen. Look for egg listed as an ingredient in a complete and balanced food rather than relying on eggs as treats.
