Cracking the Myth: Can Cats Eat Eggshells?

Yes, cats can eat eggshells. However, it should be finely ground and mixed with their food to avoid any potential gastrointestinal issues.

Eggshells are often touted as a source of calcium for cats, especially for those on a raw food diet. However, cats can only digest eggshells when they are finely ground to avoid any digestive upset. It’s important to note that while eggshells do provide a good source of calcium, they should not make up a significant portion of a cat’s diet.

It’s always best to consult with a veterinarian before adding any new food items to your cat’s diet, including eggshells. With proper preparation and moderation, eggshells can be a healthy addition to a cat’s diet.

Nutritional Value Of Eggshells

Can Cats Eat Eggshells?

Cats are obligate carnivores, meaning they require nutrients mainly from animal sources. However, eggshells are a great source of calcium and other essential minerals, which can benefit kitty’s health in many ways.

A Detailed Explanation Of The Nutritional Benefits Of Eggshells

Eggshells are an excellent natural source of calcium, magnesium, and other essential minerals that your feline friend needs to stay healthy. Here’s how these minerals can benefit your cat:

  • Calcium helps maintain bone density, heart rhythm, muscle function, nerve transmission and is vital for blood clotting.
  • Magnesium is essential for maintaining healthy bones, muscles, and nerves, energy metabolism, and protein synthesis.
  • Other minerals such as iron, zinc, and copper also play a significant role in maintaining your cat’s overall health.

Comparing Eggshells To Other Calcium Sources For Cats

Eggshells are an excellent source of calcium for cats compared to other sources such as:

  • Dairy products such as milk and cheese are not suitable for cats because they contain lactose, which cats cannot digest properly, resulting in gastrointestinal distress and diarrhea.
  • Meat and fish don’t contain as much calcium as eggshells, making it difficult to meet the recommended intake for the nutrient.
  • Commercial cat foods do contain calcium, but the amount can vary widely, and some may not meet your cat’s daily requirements.

How Much Calcium Do Cats Need?

The association of american feed control officials (aafco) recommends 0. 6% calcium on a dry matter basis for adult cats and 0. 9% for kittens. A cat’s requirement for calcium will vary depending on age, breed, and overall health.

It’s essential to note that too much calcium can be harmful, leading to kidney or urinary tract problems. Consult your veterinarian to determine the appropriate calcium intake for your cat and consider adding a small amount of ground eggshells to their diet to give them a natural source of healthy minerals.

In conclusion,

Eggshells are a fantastic natural source of calcium for cats. A small amount of ground eggshells added to your cat’s diet can provide them with the essential minerals they need to maintain overall health. Remember to consult with your veterinarian regarding the appropriate calcium intake for your cat and avoid over-supplementing with calcium.

Risks Of Feeding Eggshells To Cats

Are you a new cat owner who is curious about your feline friend’s diet? Well, cats are obligate carnivores, which means they need protein-rich meals to stay healthy and happy. But have you ever wondered if cats can eat eggshells?

While eggshells fall under the category of ‘human food,’ it’s not necessarily safe for our feline friends to consume. In this section, we will discuss the potential risks of feeding eggshells to cats.

Potential Dangers Of Feeding Eggshells To Cats

Feeding eggshells to your cat may seem like a good idea, considering that they are an excellent source of calcium. However, eggshells pose more harm than good to your feline friend. Some of the dangers that come with feeding eggshells to your cat include:

  • Eggshells can pose a choking hazard to your cat, especially if they are not finely ground.
  • The sharp edges of eggshells can damage your cat’s digestive tract, causing internal injuries.
  • Raw egg whites contain avidin, which can interfere with biotin absorption, leading to skin and coat issues.
  • Feeding your cat too much calcium can disrupt the balance of minerals in their bodies, leading to serious health issues.

The Impact Of Excess Calcium On Cats’ Health

Calcium is essential for cats’ bone growth, muscle function, and blood clotting. However, too much calcium can have adverse effects on their health. Some of the impacts of excess calcium on cats include:

  • Kidney issues: Excess calcium can lead to the formation of bladder and kidney stones, which can be painful and life-threatening to cats.
  • Urinary tract infections: High calcium levels in cats’ urine can predispose them to urinary tract infections.
  • Joint and bone pain: Too much calcium can cause arthritis and skeletal issues in cats.
  • Digestive issues: High levels of calcium in cats’ blood can cause vomiting, constipation, and diarrhea.

Other Risks To Consider

Apart from the dangers of choking and high calcium levels, feeding eggshells to your cat can expose them to other risks, including:

  • Salmonella contamination: Raw eggs can contain harmful bacteria that can cause food poisoning in cats.
  • Allergic reactions: Some cats may be allergic to eggs, leading to skin and coat issues, vomiting, and diarrhea.
  • Parasites: Feeding your cat raw eggs can expose them to parasites like tapeworms.

While eggshells may seem like a harmless treat for your cat, they pose more risks than benefits. It’s best to stick to a protein-rich, well-balanced diet for your feline friend.

How To Feed Eggshells To Your Cat

Cats are known for being finicky eaters, and owners often worry about what they can and cannot feed their cats. One such food item that raises questions is eggshells. In fact, eggshells are an excellent source of calcium and other minerals that can be beneficial to cats.

We will delve into how to feed eggshells to your cat, including preparation, quantity, and safety.

How To Prepare Eggshells For Your Cat

Before feeding eggshells to your cat, it is important to ensure they are safe for consumption. Follow these steps to prepare eggshells for your feline friend:

  • Rinse the eggshells thoroughly to remove any remaining egg white or yolk.
  • Boil the eggshells for ten minutes to kill any bacteria or salmonella that may be present.
  • Let the eggshells cool down completely before crushing them into small pieces using a pestle and mortar, or blender.

The Recommended Quantity Of Eggshells To Feed

Once the eggshells have been prepared, it is important to feed them to your cat in the right quantities. Offering too much calcium can be detrimental to your cat’s health, so it is essential to get the amounts right. The recommended quantity of eggshells to feed depends on your cat’s age and health.

Here are some guidelines:

  • For adult cats, give them half a teaspoon of crushed eggshells per day.
  • For kittens, reduce the amount to an eighth of a teaspoon until they are at least six months old.
  • If your cat is prone to urinary tract infections, it is best to avoid feeding them eggshells altogether, as the high amounts of calcium can make the ph of their urine too alkaline, increasing the risk of infection.

When It’S Safe To Feed Eggshells To Your Feline Friend

Feeding eggshells to your cat is safe as long as you follow the right preparation and quantity guidelines. However, it’s always best to consult with your veterinarian before introducing a new food item to your cat’s diet, especially if your cat has underlying health issues.

In addition, if you give your cat a balanced and complete diet, there may be no need to supplement their diet with eggshells.

Feeding eggshells to your cat can be beneficial as long as you follow the right guidelines. Remember to prepare the eggshells correctly, feed them in the right quantities, and ensure it’s safe for your cat. By doing so, you can provide your feline friend with essential minerals that promote healthy bones, teeth, and muscles.

Alternative Calcium Sources For Cats

Cats are known for being finicky eaters, and also for having several unique dietary requirements. One such requirement is calcium, an essential mineral that contributes to bone and teeth health, nerve function, and muscle function, among other things. While eggshells are a great source of calcium for cats, there are several other options available that owners can explore.

In this blog post, we will discuss alternative sources of calcium for cats, compare their nutritional value to eggshells, and provide tips on how to choose the right calcium source for your furry friend.

A List Of Alternative Sources Of Calcium For Cats

  • Fish bones: Fish bones, such as those found in canned salmon or canned sardines, are an excellent source of calcium for cats. They are also a good source of phosphorus, which is another mineral that is important for feline health. However, it is important to make sure that the bones are thoroughly cooked before feeding them to your cat to avoid any risk of bacterial contamination.
  • Dairy products: Dairy products such as cheese and yogurt contain calcium, but it is important to ensure that your cat is not lactose intolerant before feeding them dairy products. If your cat does not tolerate dairy well, you may want to consider lactose-free products or supplements instead.
  • Supplements: There are several calcium supplements available that are specifically designed for cats. These supplements come in different forms, including powders that can be added to food, chews, and capsules. It is important to follow the manufacturer’s instructions and dosage guidelines when giving your cat a calcium supplement.
  • Leafy greens: Leafy greens such as kale, collard greens, and spinach are also good sources of calcium for cats. However, it is important to note that these foods also contain oxalates, which can contribute to the formation of urinary crystals in some cats. If you choose to feed your cat leafy greens, make sure to do so in moderation and consult with your veterinarian if you have any concerns.

Comparing Nutritional Value To Eggshells

While eggshells are an excellent source of calcium for cats, they are not the only option available. Here is a comparison of the nutritional value of eggshells to some of the other calcium sources discussed above:

| Calcium Source | Amount Of Calcium Per 100G |


| Eggshells | 800-1000Mg |

| Cheese | 100-150Mg |

| Yogurt | 100-150Mg |

| Supplements | Varies |

| Leafy Greens | 100-150Mg |

As you can see, while eggshells provide the highest amount of calcium per 100g, there are several other options available that can still provide a significant amount of the mineral.

Tips For Finding The Right Calcium Source For Your Cat

  • Consult with your veterinarian: Before making any changes to your cat’s diet or adding supplements, it is important to consult with your veterinarian. They can help determine if your cat has any specific dietary requirements or underlying health conditions that need to be taken into consideration.
  • Consider your cat’s preferences: While it is important to provide your cat with a balanced and nutritious diet, it is also important to consider their preferences. If your cat is a picky eater, you may need to experiment with different calcium sources to find one that they enjoy.
  • Monitor for any adverse effects: When introducing a new food or supplement, it is important to monitor your cat for any adverse effects, such as vomiting, diarrhea, or changes in behavior. If you notice any concerning symptoms, consult with your veterinarian right away.

While eggshells are a great source of calcium for cats, there are several other options available that owners can explore to ensure their feline friends are getting the essential mineral they need.
