Can gerbils use hermit crab sand?

Yes, gerbils can use hermit crab sand as a substrate, but it's important to ensure that the sand is clean and free from harmful additives. Hermit crab sand is typically made from natural materials and can provide a suitable environment for burrowing. However, it should not be the sole substrate; a mix with other bedding materials like aspen shavings or paper-based bedding is recommended for optimal health and comfort. Always monitor your gerbils for any signs of irritation or discomfort with any new substrate.
