I have 1.1 Dasypeltis scabra, have had them for about 2 years.
I whole heartedly agree with Dr. Del's advice. Find a local food source before you get one of these animals. If you cannot find a local source then you wil need to syringe feed them which is pretty tramatic on them. Plus, the skeleton on these guys is super, super fragile and they are prone to spinal kinking if handled too roughly. I do not recommend getting baby egg eaters because of this because finding a reliable source of finch eggs is nearly impossible. Get an adult and get your hands on quail eggs and you are all set.
I wil also say that these guys are a lot more arboreal than the literature suggests so whatever you are housing them in give them lots of room to climb (and consider putting in a couple finch nests as they seem to like to hid out in those.)
