What is the maximum protein \ fat I should give my rodents? (2 pet rats that will breed for feeders and feeder mice)?Should dog food be good for the female mice? got 21% protein and 12% fat at my dog food.To my pet rats I give veggies \ leftovers \ pasta etc' but to the feeder mice I will only feed them their food, should I use my dog's food or mice only food product? Another question I have, is it alright to give my snakes rodents with tumor? I did give my corn snake 2 or 3 times female mice with tumor a few months ago.. I don't know if that was good.. he eat well and doesn't refuse anything.
