No, eco-earth is not digestible. If you look on the Facebook group "Leopard Gecko Care and Advice" you can find a post less than two weeks ago from a woman who kept her baby leo on it for a short time and it passed away in a few weeks due to impaction. She had also read it was digestible and thought it was safe. It's not.

Most people use CA in a bottle cap in the enclosure and CA+D3 to dust the feeders, others use CA+D3 for both. I use CA+D3 for both so I'm not buying 2 different calcium supplements.

I use spaghnum moss in the humid hide since leo's won't eat it.
