So I found this recipe of Solid Gold (Fit and Fabulous), and I was curious about whether or not this could be used for feeding box turtles. Namely as an additive or mix in, not as a standalone staple. The reason I think this might be an interesting option is because it contains a wide assortment of vegetables like some of the more modern dog food mixes do, so I wondered if it was more viable as a food source than older style dog or cat foods. Disclaimer: I'm still figuring out the nutritional balance for Box Turtles so this question is purely for research purposes, I'm not currently feeding this to a turtle or anything.
