Good to hear he's alright, but I'm confused... is he staying with the vet or is he back home now? 17 months isn't bad, because losing him would've been much worse, right? I wouldn't worry too much about the money, just the snake. Another thing, I know this applies to humans, but snakes I'm not sure... if there is something piercing the flesh and is relatively severe it's better to leave it in, and let the doc remove the glass then it is to do it yourself. (As removing it yourself could cause more harm, or allow blood to flow from the wound, possibly hurting the animal more...) Keep us updated on his progress!
