Can Cats Eat Eggshells?
Please read the risks below before offering any.
Are eggshells safe for cats?
Eggshells are the hard outer shell of eggs and are mostly calcium carbonate. Cats on a complete diet do not need extra calcium, and sharp shell fragments or raw shells can cause problems. Cats are obligate carnivores, so they get what they need from meat and never need eggshells. If you offer them at all, treat them as a rare, tiny extra.
How to reduce the risks if you offer eggshells
- Ask your vet before adding any calcium source
- If used, the shell should be cleaned, baked and ground to a fine powder
- Never give large or sharp shell pieces
What to avoid
- Raw shells (Salmonella risk)
- Sharp, unground pieces
- Extra calcium on top of a complete diet
How many eggshells can my cat have?
If you decide to offer eggshells despite the cautions above, give just one tiny taste and check with your vet first, especially if your cat has any health condition. When in doubt, skip it.
Signs your cat may be having a problem
Watch for vomiting, diarrhea, drooling, pawing at the mouth, loss of appetite, tiredness, a swollen or painful belly, or trouble breathing. Contact your vet right away if you see these signs, or if your cat has eaten any of the parts listed above.
Frequently asked questions
Can kittens eat eggshells?
Because eggshells need extra caution for adult cats, it is best to avoid them for kittens.

The most common result is an upset stomach with vomiting or diarrhea. Offer water, skip further treats, and call your vet if symptoms are severe or last more than a day, or if your cat ate any of the parts listed under "What to avoid".
Should eggshells be a regular part of my cat's diet?
No. We recommend not making eggshells a regular part of your cat's diet.
