    Have used this block since it came out on the market it is an easy way to feed and supplement at the same time. Less mess than other options or can be used in addition to other cricket food. Would recommend this to any cricket keeping reptile owners. Makes things easier in cricket keeping.

    If you have a reptile, especially a baby one, you need to make sure your pet receives Calcium and Vitamin D with its food. At first, I used powder, which meant I had to catch the crickets and coat them in powder before giving them to my bearded dragon. Then, I found Zoo Med Cricket Block Reptile Supplement. Now, I put the cricket block reptile supplement in the cricket container, where they feed on it. Breeders call this gut-loading, which I find a distasteful name; however, no more coating crickets. All I have to do is put the crickets in the tank for my baby beardie to get calcium and vitamins.

    I do not care for this product it is too hard and I have yet to see any crickets touch it. I even tried moistening it to no avail. Thought it would be convenient but no!
