Which probably constitute the bulk of available feeder animals . Who knows where the store gets the mice and rats and how long they have been refrigerated.
I doubt that many people will argue the point that long term storage degrades the quality of the meat. So there goes your food quality.

And just to add one more thought, the argument that captive feeder insects need to be supplemented because they don't get the variety of nutrients as their wild equivalent may be true but then rats and mice in captivity are fed a balanced diet and get little or no exercise so it would lead me to believe that they might not be completely nutritionally sound either. How much of their body mass is nothing more than fat?
