Sorry mate, i know it's hard. There are a million and one things you can know about reptiles and two million different opinions out there. Ill try to explain a little better. Basically the Aspidites genus are naturally reptile eaters but they can also eat mammals. In captivity we feed them mammals (rats,mice,rabbits) but because these animals have much higher fat content than reptiles do, we have to be extra careful. To do this, you have to pick and choose what you feed them. Rodents generally get fatter as they get older, so it is better to feed a few smaller food items rather than one large one, but this only starts to apply once you get to large and extra large rats. In saying this though, even when they are small, it is best to feed them less often than you would a Coastal or Bredli for example. I hope this helps, i'm sure you're doing a great job, but the more you know, the better keeper you will be.
