Can Cats Eat Eggs?

In this guide

Adapted from a Rover.com feature on feline nutrition.

Cats and birds have a long, well-documented rivalry — but what about eggs specifically? Eggs are a great source of protein for humans, and cats are protein-hungry carnivores, but that doesn't automatically mean all proteins are created equal for them. Cats have a different digestive system than we do, and while some human foods are harmless or even beneficial for them, others cause real problems, immediate or long-term. Here's where eggs land.

What makes eggs nutritious

Eggs are genuinely packed with nutritional value — an excellent source of protein, good fatty acids, and vitamins, and a staple ingredient in an enormous range of recipes. Alongside vitamins B12, D, and B6, eggs also supply essential minerals like iron, copper, and zinc. There's not much an egg can't do, nutritionally speaking.

So, can cats eat them?

Yes — as long as they're scrambled, boiled, or otherwise fully cooked. Cats get the same nutritional benefits from eggs that humans do, provided the eggs are cooked through. Scrambled eggs in particular are easy to digest and give cats convenient access to the protein they need for lean muscle and energy. Dr. Gary Richter, DVM and medical director of Montclair Veterinary Hospital in Oakland, California, explains that because cats are carnivores, animal protein is genuinely critical to their health, and cat food should be built predominantly around animal products.

One caveat: like humans, cats can develop egg allergies. If you're introducing eggs for the first time, watch for a few days for signs of a food allergy — irritated skin or ear infections are common indicators — and check with your vet if you notice a behavioural change.

Never serve raw eggs

Raw or undercooked eggs can carry pathogens like E. coli or salmonella, and the American Veterinary Medical Association recommends an emergency vet visit if a cat has eaten raw or undercooked eggs or other raw animal protein. A few practical precautions: keep fallen bird eggs or carcasses out of reach, wash your hands thoroughly before handling your cat's food (especially after handling other raw ingredients), and dispose of leftover food — human or cat — daily rather than leaving it out.

Yolks, whites, and shells

Egg yolks carry the bulk of the egg's nutrients and are perfectly fine for cats as long as they're thoroughly cooked — raw yolk carries the same food-borne illness risk as the rest of a raw egg. Egg whites are safe too.

Eggshells are a more surprising option: PetMD notes some evidence that they can offer a calcium boost when prepared properly. To avoid salmonella risk, boil the shells first, then crush them into fine pieces (a coffee grinder works well) before sprinkling into your cat's food.

Other healthy snack ideas

Beyond regular cat food, a handful of other options are considered safe treats — though your cat may or may not show interest, given how routine-oriented cats tend to be about food. Dr. Richter notes there's no reason cats can't have human food as long as it's nutritionally appropriate, but adds that cats are typically very specific about what they'll eat and rarely enthusiastic about dietary changes.

According to the ASPCA, these are non-toxic treat options for cats:

• Meat — cooked turkey, beef, chicken, and some lean deli meats work well
• Zucchini
• Celery
• Oats
• Carrots
• Green bell peppers
• Spinach
• Peas — often included in packaged pet food for their vitamin content
• Pumpkin
• Broccoli

Even so, cats remain carnivores at heart, and filling up on vegetables instead of a properly balanced cat food means missing out on essential nutrients. As Dr. Richter puts it, the bulk of a cat's diet should stay balanced — treats, generally, shouldn't make up a significant share of daily intake.
