Is it good to feed Emperor Scorpions pinkie mice?

I give my scorpions and tarantulas pinkie mice as a treat every so often. Pinkie mice are high in fats and cholestoral, and are good for growing or sick small critters. I've noticed a considerable difference in one of my tarantula's growth rate and size since I have been feeding her pinkie mice. But because they are high in fat, it isn't good to offer pinkies to your scorpion often. Adults can be offered bigger pinkie mice and fuzzies more than youngsters. Some scorpions won't even go after pinkie mice if they are used to a strict-insect diet. Hope this helps!
