The only time i have fed doc, is when i have given them as a snack, just to tide them over till the rabbit had defrosted abit as i had forgot to take it out the freezer. But like joel said, i wouldn't use them as a MEAL, due to the fact there is nothing on them meat wise. Best off with rabbit, chicken bits, mince, birds, fish etc, recently started given mine abit of olive oil mixed into some tuna and they love it and their coats are top notch
