Can Cats Eat Eggs?

The Verdict First: Cooked Eggs Are Fine, Raw Eggs Aren't Worth the Risk

For most healthy cats, cooked eggs are safe and a solid source of animal protein. That's why so many owners offer them as a treat: easy to prepare, appealing to smell, and usually eaten without fuss.

A common misconception, though, is that "raw is more natural." For cats, raw eggs offer nothing that justifies the risk. Cooking an egg leaves the protein and amino acids intact, so there's no reason to accept the bacterial risk of feeding it raw.

Why Cats Like Eggs

Cats are obligate carnivores, and eggs are an animal-derived food with high-quality protein and a complete set of essential amino acids. As a treat, they fit a cat's biology well.

Egg Nutritional Highlights

Keep one thing in mind, though: eggs are not a complete and balanced meal. They can add to the diet, but they can't be the diet.

Why Are Raw Eggs Not Recommended?

1. The Avidin Problem in Raw Egg Whites

Raw egg whites contain avidin, a protein that binds biotin (vitamin B7) and blocks its absorption when large amounts are eaten over a long period. A spoonful here and there is unlikely to cause a deficiency, but feeding raw egg whites regularly could eventually show up as skin and coat problems.

2. Raw Egg Yolks: Less Avidin, Still a Bacterial Risk

Some owners ask whether raw yolks are the safer half. They aren't — yolks can still carry Salmonella. For kittens, senior cats, pregnant queens, and cats with chronic illness, that risk is not worth taking.

3. The Recommendation Is Simple

Cats don't need to take this risk. Cooking an egg preserves its nutritional value and removes the danger.

What's the Safest Way to Prepare Eggs?

• Hard-boiled eggs: easiest to portion and control.
• Plain scrambled eggs (no salt, no oil): fine, but no butter, milk, or seasoning.
• Shelled and chopped: easier to mix into regular food, and harder for a cat to bolt down too fast.

Skip soft-boiled eggs, runny yolks, salted or buttery scrambled eggs, and any version flavored with onion, garlic powder, or cheese sauce.

Egg Yolks, Calories, and Special Considerations

Egg yolks are nutritious but also high in fat. Be more cautious if your cat has any of the following:

• Obesity: yolks are calorie-dense, so portions need to be counted.
• Pancreatitis or fat intolerance: too much can trigger digestive upset.
• A vet-prescribed fat-restricted diet: ask before adding egg at all.

For a healthy cat, a little cooked yolk now and then is fine — but don't increase the frequency or the amount just because it looks nutritious.

Can Cats Eat Eggshells?

Ground eggshells can serve as a calcium supplement if the shells are washed thoroughly, dried completely, and ground to a fine powder so no sharp fragments irritate the mouth or gut. If your cat already eats a complete and balanced commercial food, though, extra calcium isn't needed, and adding it can throw off mineral balance.

For a cat on a homemade diet, whether eggshell powder belongs in the recipe is a question for a veterinary nutritionist.

How Much is Too Much?

Eggs should be considered a treat, not a main meal.

• Average adult cat: about 1–2 eggs per week, adjusted for size and total calorie intake.
• Smaller or less active cats: start with 1–2 teaspoons of cooked egg per serving.
• General rule: treats should stay under 10% of daily calories.

If your cat already had freeze-dried treats, meat purée, or other rewards that day, cut the egg back accordingly.

Which Cats Need Extra Caution?

• Food sensitivities: start with a crumb on the first try.
• Overweight cats: go light on the yolk.
• Chronic kidney disease: not forbidden, but extra protein has to fit the diet your vet has set.
• Sensitive stomachs: introduce cooked egg slowly and keep servings small.
