Thanks guys!
I asked Scott about what feeding regiment would be best for them and he said weekly to bi-weekly, watching out for constipation. I am on the fence about whether or not I should wait for them to poop between meals. At this point it's been 1.5 weeks since they last ate, so I'm sure feeding will go well Friday. I may start off with a smaller meal than they should be eating just in case. They are on small mouse hoppers right now, but I have mouse fuzzies as well, so I'll just have to find something the right girth.
Their bodies are about the circumference of a woman's pinky finger now. I got a male Kenyan sand boa from Scott also and they are basically the same body size as the KSB currently.
