Eggshells are widely believed to provide a number of benefits for cats, including a calcium boost for strong bones and teeth, as well as other minerals like zinc, copper, and iron. But what happens if your cat eats an eggshell?

The short answer is that it’s generally safe for cats to eat eggshells in moderation. In fact, some experts believe that eggshells may even be helpful for cats in certain situations. However, it’s important to be aware of the risks involved before allowing your cat to eat eggshells.

Benefits of Eating Eggshells

Eggshells are a natural source of calcium, which is essential for cats. Calcium helps to maintain strong bones and teeth, as well as aiding in muscle and nerve function. In addition to calcium, eggshells also contain other minerals like zinc, copper, and iron, which can help to support a healthy immune system and promote healthy fur growth.

Eggshells may also be beneficial for cats with digestive problems. The eggshell membrane is a natural source of glucosamine, which can help to improve joint health and reduce inflammation.

Risks of Eating Eggshells

While there are some potential benefits to cats eating eggshells, there are also some risks that you should be aware of. The first is the risk of choking. Cats don’t have the same chewing ability as humans, so they may not be able to break down the shells as easily. If they swallow an eggshell that hasn’t been broken down, it could cause a blockage in their digestive tract.

In addition, eggshells can be a source of bacteria, such as salmonella. If your cat eats a contaminated eggshell, they may become ill. To reduce the risk of contamination, always make sure that the eggshells you feed your cat are clean and free of debris.

How To Feed Eggshells To Your Cat

If you decide to feed eggshells to your cat, there are a few things you should keep in mind. First, it’s important to understand that cats are unlikely to eat eggshells in their raw form. To make them more palatable, you can grind up the shells into a powder and mix it into their food.

It’s also important to remember that eggshells should only be fed to cats in moderation. Too much calcium in their diet can lead to health problems like urinary tract infections, so it’s best to limit their intake of eggshells to once a week or less.

Finally, make sure that you only feed your cat eggshells from clean, uncontaminated eggs. It’s best to avoid feeding them eggshells from eggs that have been sitting around for a while, as these may be more likely to contain bacteria.

In general, it is safe for cats to eat eggshells in moderation. Eggshells are a natural source of calcium, zinc, copper, and iron, which can help to promote healthy bones and teeth, as well as a strong immune system. However, it’s important to be aware of the risks involved before allowing your cat to eat eggshells. To reduce the risk of choking or contamination, make sure that the eggshells are ground up into a powder and only feed them to your cat in moderation.

Are egg shells poisonous?

Eggshells are the hard outer coating of an egg, protecting the contents of the egg from bacteria and other potential contaminants. While the eggshell itself is not toxic, it can be contaminated with bacteria, such as Salmonella enteritidis. This means that eating the shell of an egg could potentially cause food poisoning if the egg has been mishandled or improperly cooked.

What is an Eggshell Made Of?

The eggshell is made up of several components. It is composed of a thin outer layer of protein called the cuticle and three distinct layers underneath – the outer and inner shell membranes, and the calcified layer. The calcified layer is composed of calcium carbonate, which gives the eggshell its strength and rigidity. The inner shell membrane is a thin layer of albumen (egg white) which separates the eggshell from the egg yolk.

Are Eggshells Contaminated with Bacteria?

The eggshell is porous and can absorb bacteria and other contaminants from the environment. This means that the eggshell can be contaminated with bacteria, such as Salmonella enteritidis. To avoid the risk of food poisoning, make sure to boil eggs before eating their shells.

Can Eating Eggshells Be Harmful?

Eating eggshells may not be harmful in small amounts, but it can cause a number of health issues if eaten in large quantities. Eggshells are difficult to digest, and can cause digestive issues like nausea, vomiting, and abdominal pain. In addition, the sharp edges of the eggshell can damage the digestive tract and cause internal bleeding.

Do Eggshells Have Nutritional Benefits?

Eggshells do contain some nutritional benefits. They are a good source of calcium, protein, and other minerals. However, it is important to note that the amount of these nutrients is very small and unlikely to be significant when compared to other sources of calcium and protein.

Are There Any Other Uses for Eggshells?

Eggshells can also be used in a variety of other ways. For example, they can be used as a natural fertilizer, as an abrasive cleaner, or as an ingredient in homemade crafts. Eggshells can also be used as a sustainable material for 3D printing.

In conclusion, eggshells are generally not toxic and can be eaten in small amounts. However, it is important to be aware that the eggshell can be contaminated with bacteria and can cause health issues if eaten in large quantities. Additionally, the nutritional benefits of eggshells are minimal and it is better to obtain calcium and other minerals from other sources. Finally, eggshells have many other uses including as a natural fertilizer, an abrasive cleaner, and as an ingredient in homemade crafts.

Can pets eat egg shells?

It is a common misconception that egg shells are a good source of calcium for pets. While it is true that egg shells are high in calcium, feeding egg shells to your pet is not recommended. Egg shells contain sharp edges that can be hazardous to your pet’s health, and there are much easier ways to give your pet the calcium they need.

What are Egg Shells?

Egg shells are the outer shells of the egg, made up of mostly calcium carbonate. Raw chicken eggs are the most common source of egg shells, but other types of eggs such as duck and quail eggs also contain shells. Egg shells are high in calcium and can provide an important source of minerals for animals, but they can also pose a danger to pets.

Are Egg Shells Safe for Pets?

In short, the answer is no. While egg shells are high in calcium, they contain sharp edges that can be hazardous to your pet’s health. Additionally, the calcium in egg shells is not easily absorbed by the body and can be difficult for pets to digest. For these reasons, it is not recommended to feed egg shells to your pet.

What are the Alternatives to Feeding Egg Shells?

If your pet needs more calcium in their diet, there are much easier and safer alternatives to feeding them egg shells. Commercial pet foods are often fortified with calcium and other minerals, so make sure to check the labels before making a purchase. You can also look for supplements specifically designed for pets, such as calcium chews or powders.

Can Dogs Eat Egg Shells?

Although it is not recommended to feed egg shells to your pet, some veterinarians may advise it if your dog is deficient in calcium. If this is the case, you should only feed your dog crushed egg shells. Be sure to boil the egg shells before crushing them to make sure they are free of bacteria. Additionally, you should only feed your dog small amounts of egg shells and monitor them closely for any adverse reactions.

Do egg shells dissolve in stomach?

When it comes to eggs, one of the most commonly asked questions is “Do egg shells dissolve in stomach?” This is because the eggshell is made of calcium carbonate, a mineral that can easily be dissolved in stomach acid. So, the answer to this question is yes – eggshells can dissolve in the stomach.

But how does this happen? Well, the stomach contains hydrochloric acid, which is a highly corrosive substance. This acid is produced by the stomach in order to break down food and absorb nutrients. When an eggshell is exposed to this acid, the calcium carbonate in the eggshell will begin to dissolve.

The Stomach Acid and the Eggshell

Due to the acidic environment in the stomach, the eggshell will slowly start to dissolve. This process is known as “calcification”. As the eggshell dissolves, the calcium carbonate in the eggshell will be broken down into calcium ions, which are then absorbed into the body.

The process of calcification is actually quite slow, and it can take several hours for the entire eggshell to dissolve. The rate at which the eggshell dissolves depends on the amount of stomach acid present. If there is more acid in the stomach, the eggshell will dissolve faster.

Why Is Calcium Important for Health?

Calcium is an important mineral for our bodies. It is necessary for healthy bones, teeth, and muscles. It also helps regulate the body’s pH levels and helps to reduce the risk of osteoporosis.

Eating eggs is an excellent way to get your daily dose of calcium. The eggshell is made of calcium carbonate, so when the eggshell is dissolved in the stomach, the calcium ions are absorbed into the body.

Are There Any Risks Associated With Eating Egg Shells?

Although eggshells can dissolve in the stomach, there are still risks associated with eating them. For example, if the eggshell pieces are too large, they can cause blockages in the digestive tract. This can lead to abdominal pain and vomiting.

In addition, there is a risk of salmonella poisoning if the eggshell is cracked or damaged before consumption. Eggshells can also contain bacteria and other germs, so it is important to always make sure that the eggshells you eat are clean and free from contamination.

In conclusion, eggshells can dissolve in the stomach due to the presence of hydrochloric acid. This process is known as “calcification” and it can take several hours for the entire eggshell to dissolve. Eating eggs is a great way to get your daily dose of calcium, but it is important to make sure that the eggshells are clean and free from contamination.

Do egg shells hurt worms?

When it comes to composting and vermicomposting, one of the most asked questions is whether or not eggshells hurt worms. While it is true that eggs can contain bacteria and other pathogens, it is not necessarily the case that egg shells hurt worms. In fact, eggshells can provide a variety of benefits for the worms and can even help to create the perfect environment for them to thrive.

Benefits of Eggshells for Worms

Eggshells provide a source of calcium to reduce the acidity of the compost. This helps to create a more balanced environment for the worms and prevents high acid conditions that can harm the worms. Additionally, crushed eggshells provide grit to aid in the worms’ digestion. And, it is believed that eggshells help worms in the reproductive process as well.

How to Use Eggshells to Help Your Worms

It is best to grind or crush the eggshells before adding them to your compost or vermicompost bin. This will help break them down more quickly. You can use a mortar and pestle, a blender, or even a coffee grinder to get the job done.

It is also important to rinse the eggshells in order to remove any bacteria or other contaminants. This will help keep your worms safe and healthy. After you have rinsed the eggshells, let them dry before adding them to the compost or vermicompost bin.

How Much Eggshells Should You Use?

When adding eggshells to your compost or vermicompost bin, it is important to use them in moderation. Too much calcium can be harmful for worms and can disrupt the balance of their environment. A good rule of thumb is to use about 4-8 eggshells per quart of soil.

In conclusion, eggshells can actually be beneficial for worms and should not be feared or avoided. As long as you follow the steps outlined above, you can safely add eggshells to your compost and vermicompost bins. Eggshells are a great source of calcium, grit, and other nutrients that help to create the perfect environment for worms to thrive.


In conclusion, eggshells are an excellent source of calcium and other minerals that can benefit your cat’s bones and teeth. If your cat does happen to eat an eggshell, there is no need to worry as the shell is unlikely to cause any harm. However, it is best to avoid offering eggshells to your cat as they are not particularly appetizing and may even put your pet off from eating their regular food. If you are concerned about your cat’s diet, talk to your veterinarian who can recommend the best supplements and foods to ensure your pet is receiving the right nutrition. Above all, it’s important to remember that your cat’s health should always be the priority.
