When I took Etosha 6 Mon old female veiled to the vet she said to gutload with t Rex calcium plus food for crickets. I just received it. Sounds like I keep the cricket colony going with fresh foods like I am doing now but feed this for 24 hours prior to feeding them to Etosha. Does anyone else use this? Is it better than fresh foods? I guess I could also rotate this in a few days a week. I dust daily with repashy calcium with loD. I assume all vitamins are in that too. She had a clean fecal fortunately so happy with that.
