Yeah...unfortunately none of the commercial hedgehog foods are any good, really.
Honestly, Spike's really is the best one available & will continue to be unless a decent one comes out. And you can't get Spike's in a pet store, and it's still ridiculously expensive for the medium quality. Hedgehog food as a whole is pretty disappointing! It's such a shame that there are still pet stores and breeders (and vets!) that insist it's better for them than cat food.
