I guess I would add a couple cautions: Make sure you have a provider of the littlest pink mice. That's the only thing a corn that size is going to be able to eat. And, yes, you might have trouble getting it to eat, but persistance pays off.

Next, make sure you have a cage that's escape-proof! These little guys can slip out of the smallest, tiniest little cracks! A cage with a lift off top probably isn't the best. If you use tubs, you might want to get some clips to hold the cage closed. Seriously, I've lost a baby milk snake... I still have no idea how he got out of that cage!

Other than that, you should definitely ask the shop keepers about his past, his parents, where he comes from, how he's feeding, what he's eating, etc. If they seem to be avoiding answers or some of the things they're telling you don't mesh, I'd walk away. BUT, if everything they're saying matches the caresheets you find online, and their set-ups are as prestine as you say, I say... GO FOR IT!

We always say around here that you should wait until you find a snake that catches your heart... if this little guy does and you think you can make it work, well, why not?
