What Fizzylady said. They are pretty small. Even the large aren't really that big. I feed Harley who is 8 inches long the large ones and she pretty much woofs those down in 1 or maybe 2 chews. I started her on mediums and unless they were the bigger of the mediums, she would ignore them but then again she seems to ignore anything that is small. She likes her dubias big and her phoenix worms big. She is spoiled and won't even eat crickets anymore :?
