Herp Diner Crickets are canned crickets. The special thing about Lucky Reptile canned food is that cuttlefish bone powder as source of calcium has been added to most kinds including Herp Diner Crickets. Consequently these crickets have an optimal Calcium/Phosphorous ratio and are especially formulated to satisfy the reptiles need. The special cooking process ensures good acceptance by the animals. A positive side effect of the can is that it makes feeding very easy: open can and spoon out some crickets, that is it. Herp Diner Crickets are readily accepted by most insect eating lizards (especially Bearded Dragons) and birds and provide the animals with beneficial calcium. They are also a great addition to the diet of turtles.
