You know, if your not going to be happy with the animal, sell it to someone else. At this point in time, your the "annoying customer" (at least that's it seems that way in his emails back to you).

I'd hate to see you get screwed over if you sent the animal back to him and he decides to start a grievance using these email's as some sort of leverage and proof of your unapproval if that animal were to get to him in less than 110%.

It's far fetched I know... Personally... I would walk away. I'm pretty fed up with the dancing around myself that I think his attitude so far isn't worth making the snake take another long journey at your expense if something were to happen.
