DIY Calcium Blocks

Provide your tortoise with calcium! Combine calcium carbonate powder and water in a bowl. Spoon the mixture into the cups of a muffin tin. Rinse the bowl and spoon outside with a garden hose. Bake the blocks, pull the oven shelf out and use a paper towel to wipe the excess liquid off the top of the blocks, then finish baking the blocks. Allow the pan to cool, then remove the blocks from the pan and leave them on a cookie rack overnight. Put a block in your tortoise’s habitat and store the remaining blocks in a sealed bag.

Ingredients: food-grade calcium carbonate or additive-free agricultural lime, and water
