Can cats eat eggs? Eggcellent advice from Untamed!

Cats love being treated like one of the family when it comes to food.

Even though their regular diet may consist of commercial dry, semi-moist, or wet food, cats can often confound you with the most bizarre eating habits.

Felines’ natural curiosity makes them want to try anything you are eating—be it cheese, chocolate, bananas, or strawberries. Eggs could easily be your cat’s choice of a treat to complement their regular diet.

In this case, you need to understand the benefits and potential risks involved as eggs are not part of your cat’s diet.

Can cats eat eggs at all? Read on and find out how to tailor-make a meal plan to keep your feline healthy and happy.

What’s in an egg?

Eggs are highly nutritious, being made up of:

Animal protein
Animal fat
Vitamins and minerals

Animal protein

As obligate carnivores, cats have evolved to process animal protein considerably better than vegetables. A typical chicken’s egg contains around six grammes of protein. This nutrient consists of amino acids—such as taurine—a cat is supposed to metabolise to form the combinations it needs for:

Muscle development
Skin and coat health
Organ maintenance

Unfortunately, there’s not enough scientific evidence that cats can benefit from egg proteins. Wild felines eat eggs rarely, if at all, which may mean that the available nutrients are incompatible with a cat’s digestive system.

Protein quality for cats is measured by its biological value (BV), which determines what percentage of amino acids a feline can metabolise.

Of all the protein sources available, eggs are the non-plus-ultra for humans, as can be seen by their BV compared to other proteins. The table below represents bioavailability for people, which prompted certain nutritionists to assume that the values are the same for all mammals, including cats. Once again, there are no relevant studies that back up such claims.

Protein source	Biological value
● Egg	100%
● Chicken	98%
● Salmon ● Sardines ● Prawns ● Tuna	94%
● Beef ● Pork ● Ham	87%
● Soya	68%
● Wheatgerm ● Corn ● Sweetcorn ● Other vegetable proteins	Below 65%

Animal fat

Fat is an excellent source of energy for your cat—second only to proteins—and eggs are rich in it.

With around five grammes of animal fat in a standard chicken egg, your cat is supposed to get a considerable number of calories in a comparatively small package.

Animal fat also delivers the fatty acids, including:

Arachidonic acid
Linoleic acid
Omega-6 and omega-3 fatty acids

These help maintain cell membrane structure and regulate inflammatory responses.

Animal fat is also great-tasting to your cat’s palate—this may be the reason your breakfasts are disturbed by headbutting and incessant screaming.

Keep in mind that high-calorie content in eggs is not suitable for every cat, especially indoor pets. Cholesterol is another concern because it can lead to chronic cardiovascular diseases in felines.

Vitamins and minerals

One standard chicken egg contains almost all the vitamins and minerals a cat needs daily.

Eggs are particularly rich in:

Vitamins A, B2, B5, and B12
Iron
Phosphorous
Selenium
Choline

All these should help cats’ organs function correctly. Since there’s no proof that wild cats are inclined to eat eggs, it’s not safe to assume that an egg can be a vitamin and mineral cocktail for your kitty. All essential micronutrients are present in meat, so it would be wiser to stick to a meat-based diet and use eggs as occasional treats or skip them altogether.

Is raw egg good for cats?

As most humans know, it’s not all good news with eggs.

Raw eggs are a breeding ground for countless harmful bacteria, the most dangerous of which are:

Salmonella
Listeria

Salmonella

Salmonella bacteria in raw eggs can cause severe gastrointestinal problems for your cat.

A cat’s digestive system contains millions of bacteria, both good and bad. Under normal circumstances, the bad ones, such as salmonella, are kept in check by beneficial microbes, like bifidus and lactobacillus.

If your cat receives a dose of salmonella from a raw egg, the harmful bacteria can gain the upper hand, resulting in:

If left untreated, your feline can quickly experience:

Severe dehydration
Unwillingness to eat
Rapid weight loss

While most problems with a sensitive stomach clear up once the pathogen has passed through your cat’s system, gastrointestinal issues lasting more than 24 hours can have serious consequences.

If cats do not eat for more than a day, their systems begin to mobilise fat reserves to deliver energy. The sudden flood of fat can overwhelm a cat’s liver, leading to hepatic lipidosis or the build-up of fat deposits around the liver.

Treatment to repair liver damage can last up to eight weeks and demands strict veterinary supervision, as well as a carefully controlled diet.

Listeria

The symptoms of listeriosis are similar to those of a salmonella infection, including:

Lethargy
Diarrhoea
Fever
Nausea

Listeriosis can lead to death in a matter of days.

Are any particular cats at risk from raw eggs?

While some believe that eggs are a great source of protein and fat for cats, everybody agrees that raw eggs are dangerous. Only cooking can destroy potentially harmful bacteria.

You should be particularly careful in serving raw eggs to:

Kittens and growing cats
Mature and senior cats
Cats with comorbidities

Kittens and growing cats

Even after they transition to solid food, kittens’ immune systems are not fully developed.

Their digestive systems only mature after around four months, and the immune system follows the same pattern.

Before this point, kittens are particularly susceptible to gastrointestinal problems that can negatively affect their weight gain and development.

Raw eggs in your kitten’s diet should be avoided at all costs.

Mature and senior cats

As a cat goes past the age of ten, the immune system and digestive tract become less efficient. It leaves older cats prone to tummy upsets that can destabilise their already ageing organism.

The knock-on effect of gastrointestinal issues brought on by eating raw egg can be that your older cat stops eating and loses weight quickly.

Cats with comorbidities

Cats with any kind of chronic condition need to be treated with care.

Illnesses that could be made considerably worse by a bout of egg-related gastrointestinal problems include:

Diabetes or pancreatitis
Hyperthyroidism, typically accompanied by an insatiable appetite without weight gain
Urinary tract infections (UTIs), such as cystitis or bladder stones
Pre-existing digestive problems, such as constipation or irritable bowel syndrome

Feeding raw eggs as a treat can upset the balance of any diet or food regimen prescribed by your vet. The best advice is to stick to whatever has been recommended to ensure a quick recovery and no harmful side effects.

Raw food should generally be avoided, particularly if you prepare your cat’s meals at home. Raw eggs, raw chicken, and other raw meats may not only cause gastrointestinal problems for your cat but lead to cross-contamination within your family.

Can cats eat cooked eggs?

Cooking destroys most harmful bacteria, so you can offer your cat cooked egg as a treat.

Two common mistakes with boiled eggs are:

Overseasoning the egg
Feeding your feline too much fat

Overseasoning the egg

Cats have a very different sense of taste from humans.

As omnivores, we have evolved to enjoy well-seasoned or taste-intensive food, using generous amounts of:

Salt
Pepper
Herbs and spices
Sugar

Cats have considerably simpler tastes because their natural diet consists of small rodents, birds, snakes, or lizards.

Cats are also sensitive to too much seasoning, particularly with salt. In quantities over 0.2% of their total diet, salt can become toxic to cats, inducing vomiting and causing kidney damage.

If you serve cooked eggs to your cat, they should be unseasoned—feeding from your breakfast plate is not recommended.

Feeding your feline too much fat

Even though fat is an excellent energy source for cats, too much can cause weight problems and eventual liver damage or pancreatitis.

You can minimise the fat content by only using the white—this is an excellent protein source and contains almost no fat.

However sensible this may seem, you may find your cat craves the smell and taste of the fat in the yolk. Good luck fighting that battle.

Do cats eat eggs in the wild?

Although it is not common, cats have been known to raid birds’ nests and eat the eggs they find there.

No statistics exist for how prevalent this is in the wild, but it is known that eggs can cause food allergies in cats.

Allergic reactions to food occur when a cat’s body mistakes an ingested protein for a harmful invader and mounts an immune response.

Allergies usually manifest as patches of red pustules on the skin, which can itch terribly, and cats often try to lick the problem away, causing raw, bald patches.

The only cure for a food allergy is identifying and removing the offending protein from the cat’s diet.

In the wild, this is impossible, but your indoor cat is a slightly easier proposition. If your cat breaks out in skin irritations after eating an unusual food such as egg, you can simply remove the culprit from the menu.

The problem will usually sort itself out, although any bald patches may take several weeks to grow back.

What is the alternative to eggs?

If your cat is partial to sharing your fry-up, you should try experimenting with high-quality regular food to stifle the craving for extra fat and protein from eggs.

The ideal diet for a cat is made up of:

A high proportion of meat
Some animal fat to deliver calories and taste
A low to zero carbohydrate content
Adequate vitamins and minerals

A high proportion of meat

The best cat foods are grain-free and contain only meat as a protein source.

Many commercial cat foods use grains and cereals to bulk the product and make it cheaper to manufacture, but these are inefficient protein sources.

If you notice your feline constantly begging for eggs, this may come from their sensing a need for more protein or fat than their regular food is delivering. This behaviour is similar to that displayed by cats eating grass (or cat parents craving something sweet).

Animal fat to deliver calories and taste

If your cat’s regular food contains little animal fat, it may use carbs to deliver calories instead.

It is not the healthiest option. Carbs deliver fast-release energy, but any calories that are not burnt quickly are stored as fatty cells. The result is often an overweight feline, particularly in the case of indoor or neutered cats.

Low-fat content may also negatively affect palatability—cats may crave eggs because the taste of their regular food doesn’t do it for them.

In either case, food with a higher percentage of animal fat is healthier and more likely to drive your feline wild, meaning that eggs don’t get a second glance.

A low carbohydrate content

Carbs are a major cause of obesity in cats. They can also be responsible for gastrointestinal problems, overworked pancreatic systems, and problems with energy regulation.

Cats on foods rich in carbohydrates often experience bursts of energy directly after eating, followed by lethargy as their bodies are flooded with insulin to regulate blood sugar levels.

This lethargy, combined with the storage of unused calories as fat, can create a vicious circle of overeating and inactivity.

Healthy cat food should contain only tiny amounts of carbohydrates, if any at all.

Adequate vitamins and minerals

While eggs are excellent sources of vitamins and minerals, cats can get what they need from other sources that already form part of a healthy cat diet.

The best alternative sources of vitamins are:

Vitamin type	Sources
Vitamin A	● Liver ● Fish ● Butter
Vitamin B complex	● Meat ● Milk ● Liver
Vitamin D	● Liver ● Kidney ● Fish oil
Vitamin E	● Liver ● Wheat germ oil ● Milk ● Butter

Meat is also an excellent source of essential minerals. For example, the liver covers all the nutritional bases without the need for eggs in your cat’s diet.

How can you tell if cat food is good?

Everything you need to know to judge the quality of cat food is on the label.

The two most important information sources are the:

Ingredients list
Guaranteed analysis

Ingredients list

The ingredients list should tell you exactly what is in the product, and the ingredients have to be set out in descending order of volume.

Good cat food has meat as its first ingredient, and the more defined the description, the better.

You should try to avoid products with phrases, such as:

“Meat” (without saying what animal has provided it)
“Animal derivatives,” as this could include hooves, beaks, and other unpleasant body parts

After a clearly recognisable meat source at the top of the list, you should check for a long list of different types of grain. In many products, you may see different variations of the same cereal, such as:

Ground yellow corn
Corn gluten
Corn meal

These are all one ingredient, but splitting them means that each ingredient makes up a smaller proportion of the product. If grouped, the corn content of the product may be larger than the amount of meat.

The best ingredients lists are:

Short
Concise
Free of complicated chemical names and additives you don’t recognise

Guaranteed analysis

The guaranteed analysis tells you how much of each nutrient group is in the product, including:

Protein
Fat
Carbs
Moisture

Read alongside the ingredients list, it shows you how good the product is. The ideal values you should look for are:

Nutrient type	Ideal percentage
Animal protein	More than 50%
Fat	Up to 20%
Carbs	Less than 3%

The product is of high quality if you can see:

A concise ingredients list
Meat as the first ingredient
High percentage of protein in the analysis
