High protein is not needed for dubia roaches. A varied grain/veggie- fruit based diet supplies plenty of protein. Give them a bit of cat food once in a while thrown in with other foods. Feed mostly the former and all is well. I have Thousands of dubia and I have found protein level of 12-13% is needed to prevent cannibalism. I market a grain based feed that is slightly lower and provides enough protein without causing toxemia or uric acid build up.
