Premium cricket gut-Loader, vitamin & mineral concentrate. The same formula that Fluker Farms Uses. Fluker's High-Calcium Cricket Feed is a premium formula designed for "gut-loading" crickets to increase their vitamin/mineral content prior to offering them as prey to your pet. This allows insect-eating pets to benefit not only from the nutritional value of the insect itself, but from the insect's nutrient-rich gut content as well. Available Size: 11.5 oz. (326g)
