Can dogs and cats eat egg shells?

CarefulGround shells are a calcium source some people add; raw whole shells can cut.
Only if your vet suggests it for a home diet, finely ground and baked. Otherwise skip.
If they ate it
Offer water, skip the next meal, and call your vet if vomiting or diarrhea lasts more than a day or your pet seems unwell.
Careful for dogs means: fine in a small amount, prepared as described, and not for every pet; the details say when to skip it.
