Alright, my fears have been subdued haha. If it clarifies anything, he's been eating the frozen "Small Adult Mice" from Arctic Mice. Well it's a good thing he's not underweight then. I've personally got no problem with him being a bit on the small side, he's a pet, not a breeding machine. Soon after I first got him I did try feeding him every 4 days, but when my parents found out they threw a fit haha. Once I have a source of income my snakes will be fed a wee bit more.
