Meal Replacement Powders are a fantastic diet for many types of reptiles, especially geckos. These are often popular for Day Geckos and Crested Geckos, but can also be used for many other omnivores as well. These feeds just need mixing with water to provide a nutritious diet, and come in a huge choice of flavours, so you can either stick with what you know they like, or ensure they get to try a bit of everything!
