Meal Worm Diet?

If by mammalian tissues you mean hair, yes. But pinkies don't have hair. The concern with mice is that they are high in fat, and over feeding them has been linked to lipid opacity in Horned Frogs. Another concern is that their high vitamin A content may cause problems with metabolizing calcium. Dip the pinky in calcium supplement prior to feeding.
I would would say a couple a month for a juvenile would be fine.

Ra had pretty much covered everything. I would just like to add that dipping the pinky rump first will be a more humanely way to go. I would recommend not dipping it head first cuz the fine powder will get into the respiratory sinus and make the pinky suffer unnecessarily.
