Overview
Eggshellent Calcium from Pet's Friend is a fine eggshell powder calcium supplement made for dogs and cats, sold in a 6 ounce container aimed at supporting hip and joint health rather than human use.
Ground eggshell is a natural calcium source some pet owners add to homemade or commercial food when a vet recommends extra calcium. Because the powder comes from eggs, it carries an egg allergen, worth noting for any pet with a known egg sensitivity. No seller description or customer reviews accompanied this listing to confirm exact use instructions.

Who it's for
