You don't really need the high protein dog or kitten food IMO.... It's just a waste of money, if you ask me.... Poultry mash is good and satisfactory.... Pretty Bird Food is good, too. These are roaches that feed on mostly vegetation where they come from, so they don't need exceeding high amount of protein. They will thrive on veggies and fruits alone from personally experience. Feed the poultry mash or Pretty Bird Food along with veggies and fruits and you'll have thriving colonies in no time. They seem to like cantaloupe, a lot, from what I have seen. It's like Viagra for them, like oranges.
