I live with my daughter and she is OK with crickets but not roaches. Considering the crickets do escape now and then, I have the same concern. I know the crickets have a limited lifespan and my cats usually find the escapees, anyway. I don't know if that would be true of the roaches. My dragons are picky when it comes to new food and have resisted anything other than crickets, romaine, butternut squash, and mangos. I supplement with calcium and vitamins. They are older rescues and the vet says their diets are OK so I guess I will stick with them. Dubia's would be a lot easier, though. Thanks for the suggestion.
