Can Cats Eat Eggs? What You Need to Know!

More than most other domesticated animals, cats, even household cats require the most protein. If Fluffy is looking a little too ‘fluffy,’ then you might need to increase the amount of protein in his diet. A portion of nutritious cat food should contain about 25% protein. But if you’re looking to supplement your cat’s diet with a little extra protein beyond their normal food, there are several ways to do that. Giving your cat eggs can be one of those ways. The short answer is “Yes, cats can eat eggs.” But there are some definite caveats.

Is Cooked Egg Good for Cats?

The first caveat is that the egg has to be cooked. Raw and undercooked eggs can contain salmonella and E-coli which can lead to food poisoning. In addition to the bacteria that can be found in raw eggs, egg whites contain a protein called avidin which can bind strongly to Vitamin B7 (also called Biotin). This can prevent the body, as well as a cat’s body, from absorbing Biotin. In humans, lack of Biotin is usually associated with those who suffer hair loss. It is similar in cats, where a lack of Biotin negatively impacts their coat health. When eggs are cooked, avidin’s binding abilities are weakened. This means that Biotin can be absorbed by the body easier.

Yes, cats in the wild will indeed eat raw eggs. But their digestive systems are more accustomed to it. They can handle it better than our coddled and domesticated fur babies

Can Cats Eat Scrambled Eggs?

If you are going to give your cats eggs, they need to be cooked. Scrambled eggs are one of the best ways to give your cat eggs, especially if you want to mix it in with some kibble for her to eat. But they should be cooked properly and completely and should not be runny. Other options are pieces of hard- or soft-boiled eggs.

Is an Egg a Good Meal for a Cat?

Since cats need a balanced diet, they need to eat food that is geared toward giving them multiple nutrients. While eggs are high in protein, good fats, and calcium, they are low in carbohydrates. Most of the energy that cats need comes from animal protein, but they still require carbs. You don’t have to worry about this if you buy premade cat food which is geared toward supplying cats with all the nutrients they require. So, no, an egg is not a meal replacement for a cat, only a supplement.

What Is Bad for Cats to Eat?

As it pertains to eggs, cats should only consume completely cooked eggs. But this cannot be a large part of their diet. A cat should eat no more than 10% in eggs (about 1 egg per day) of their overall daily caloric value. It’s true that cats are obligate carnivores. That is, they cannot go without meat or animal protein. This means that eggs fit right into their diet because all of their protein is animal protein. But you need to see how your cat responds to the taste first. Equally important is how their body responds. You might find it doesn’t quite agree with them. Just remember to introduce it gradually and moderately.

Are Eggshells Good for Cats?

It’s not safe for a cat to eat a plain cracked eggshell. It can be a choking hazard and hard to digest. However, eggshells are packed with calcium. You can serve it to your cat crushed and mixed in with their food as a dietary supplement. Check out this simple way to make eggshell powder. You can boil the eggshells to clean them, dry them out in the oven, and grind them up into a fine powder in your food processor. You can also put it in a shake for yourself!


Giving your cat some eggs can be a great way to make sure they are feeling strong, energized, and that they have a shinier coat. However, this is by no means a meal replacement. Keep in mind that they may not like it, or they may have an allergic reaction. Whenever you are going to change your cat’s diet, always introduce things slowly to see their response. You might find that eggs actually become a little treat for your feline friend, something you can give as a reward!
