Is It Safe? Can Cats Eat Raw Eggs – What Vets Really Say

Can cats eat raw eggs? While it might sound like a harmless or even healthy treat, giving your cat raw eggs can actually do more harm than good. Raw eggs are rich in protein and healthy fats, but they come with risks like bacterial infections and nutrient imbalances that every cat owner needs to be aware of.

Stat to consider: According to the CDC, raw eggs are responsible for over 79,000 cases of foodborne illnesses each year in the United States alone . If those numbers worry you, they should—because your cat isn’t immune to the same bacteria that can make humans sick.

Here’s what you need to know before adding raw eggs to your cat’s bowl:

Raw eggs may contain salmonella or E. coli, which can cause serious illness in cats.
The avidin found in raw egg whites blocks the absorption of biotin, a vital B-vitamin.
Cooked eggs can be a healthy alternative, providing similar benefits without the dangers.

The Nutritional Composition of Raw Eggs

Vitamins and Nutrients in Raw Eggs

Raw eggs are nutrient-dense and may look like a natural protein booster. Here’s what they contain:

High-quality protein: Great for maintaining muscle mass.
Vitamin A: Essential for skin and vision health.
Folate and Riboflavin: Supports red blood cell production and energy.
Iron and Selenium: Supports immune function.
Choline: Crucial for brain health.

While this sounds impressive, the truth is many of these nutrients are less bioavailable when eggs are raw. Cats may not absorb them efficiently.

Comparing Cooked vs. Raw Eggs for Cats

Cooking eggs makes a big difference:

Cooked eggs destroy bacteria, making them safer.
Cooking deactivates avidin, allowing biotin to be absorbed.
Cats can digest cooked proteins more efficiently.

Table: Nutritional Breakdown of Raw vs. Cooked Eggs

Nutrient	Raw Egg (per egg)	Cooked Egg (per egg)
Protein	6g	6g
Biotin	Low (blocked by avidin)	High (bioavailable)
Bacteria Risk	High	Low
Digestibility	Medium	High

Potential Health Risks of Feeding Raw Eggs to Cats

Salmonella and E. Coli Infections

Raw eggs can harbor harmful pathogens. Cats are not immune and may suffer from serious infections.

Common symptoms of salmonella or E. coli include:

Vomiting and diarrhea
Loss of appetite
Fever and fatigue
Dehydration

If untreated, infections can spread from pets to humans (zoonotic transmission), especially dangerous for children, elderly, and immunocompromised individuals.

Biotin Deficiency Caused by Avidin

Avidin, found in raw egg whites, binds to biotin and prevents its absorption. Over time, this leads to biotin deficiency, which negatively affects:

Skin health – Dryness, itching, flakiness
Coat appearance – Dull, thin fur
Nervous system – Sluggishness, irritability
Growth and development in kittens

Symptoms of Egg-Related Illnesses in Cats

Illness	Symptoms	Severity
Salmonella	Vomiting, fever, diarrhea	High
Biotin Deficiency	Hair loss, dull coat, fatigue	Moderate
E. Coli Infection	Diarrhea, lethargy, abdominal pain	High

Do Raw Eggs Offer Any Benefits to Cats?

Protein Boost and Natural Fats

There are potential upsides if used correctly, though they’re not worth the risk for most pet owners.

Egg yolks contain beneficial fats, vitamin D, and choline.
The protein supports muscle repair and maintenance.
Raw yolks (excluding whites) offer trace minerals and healthy cholesterol.

When, If Ever, Raw Eggs Might Be Helpful

For undernourished cats or those recovering from illness, vets may recommend limited raw yolk.
Only under supervision, and never more than once every two weeks.
A safer option? A pasteurized raw yolk—though still not ideal.

Raw Egg White vs. Raw Egg Yolk – Which Is Worse?

The Role of Avidin in Raw Egg Whites

Egg whites are the real concern due to avidin, which:

Blocks biotin absorption
Interferes with normal enzyme function
Can cause long-term skin and nerve issues

Nutrient Density of Egg Yolks for Felines

Egg yolks are packed with:

Fat-soluble vitamins (A, D, E, K)
Biotin and folate
Omega-3 and Omega-6 fatty acids

But raw yolks still carry a risk of salmonella, so cooked yolk is your safest bet.

Vet Opinions: What Do Experts Recommend?

Insights From Veterinarians and Pet Nutritionists

Vets universally advise caution:

“Raw eggs can introduce harmful bacteria into a cat’s system,” says Dr. Sarah Wooten, DVM.
The American Veterinary Medical Association (AVMA) discourages feeding raw animal products to pets.

How Often Is Too Often? Frequency Guidelines

Occasional Treat or Diet Staple?

Feeding raw eggs regularly is not safe or recommended. If at all, it should be:

Yolk only
Cooked fully
No more than once per week

Vet-Approved Feeding Recommendations

Avoid raw eggs entirely unless under direct veterinary guidance.
Use alternatives such as biotin-rich supplements, cooked lean meats, or approved treats.

Raw Eggs in Homemade Cat Food: A Risky Choice

While homemade diets are trending, many of them are unbalanced and unsafe.

Raw eggs may further increase the nutritional risk.
Missing nutrients like taurine and biotin can lead to deficiencies.
Always consult a vet nutritionist when preparing homemade meals.

Natural Sources of Biotin to Balance the Diet

Instead of raw egg whites, try:

Cooked liver – A natural biotin-rich food
Sardines – Packed with healthy fats and biotin
Sweet potatoes (cooked, peeled) – Low-calorie source of biotin

These options help maintain coat health and prevent skin issues.

Myths About Cats and Raw Diets

There’s a popular belief that raw = natural = healthier. But that’s a dangerous myth.

Wild cats have shorter lifespans and tolerate bacteria differently.
Domestic cats lack the same immune resilience.
Food safety today matters more than “natural” instincts.

Conclusion – Final Verdict on Raw Eggs for Cats

So, can cats eat raw eggs? Technically, yes—but should they? Absolutely not. Raw eggs carry risks that are simply unnecessary given the safer, cooked options available. From bacterial infections to nutrient absorption issues, raw eggs can jeopardize your cat’s health. Cooking eggs not only eliminates harmful bacteria but also boosts the nutrient availability. If you’re looking to treat your cat, cooked eggs, commercial high-protein treats, or vet-approved supplements are the way to go.

Pro Tip:

For a safe, skin-boosting treat, mix a teaspoon of cooked egg yolk and a dash of salmon oil into your cat’s meal once a week. It’ll help their coat shine—without any of the health risks of raw eggs!
