You can feed it pinkies just not so often, in moderation they are not bad for him. I give mine pinkies when they are babies and small juveniles about once a month and give small fuzzy mice to my adults. Its just not good to give them to him as staple pretty much. The fat content can cause liver failure and the high protein can cause it to develop cloudy eye which this kind of cloudy eye is irreversible and can eventually cause blindness. And if your worried about impaction from bones the pinkies bones would be a lot easier to digest and easier on his digestive system then a full grown mouse.
