Muddoc, while I am truly sorry the vet didn't agree to do the surgery, do you understand there is a reason WHY he refused to give you a suture kit? Because you are not QUALIFIED nor TRAINED to do surgery. If it were that easy, sterile sutures kits would be available in the local pet store or CVS!
If you had a dog that you felt needed surgery and the vet declined due to the fact the surgery may not work or the dog could suffer more, would you take the dog home and do it yourself?
Even if snakes do not feel pain in the sense that we do, I am willing to bet the feel something. There was a gentleman here who posted of a snake being chewed by a mouse left in the cage. Just about EVERYONE stated this guy should have taken the snake to the vet and some were pretty nasty in how they said it. How is THIS any different? Just because the guy breeds them? He is STILL not a vet!
Again, just because this proceedure done the way he did it worked doesn't make it right. Even if it worked out well 9 of 10 times, the one time that a snake gets an infection due to lack of sterility and proper techniques by someone following his video is one time to many. And thus, irresponsible to show it.
Muddoc, you say this happened to you this past Sat. I truly truly wish you and your snake all the best! However, if you find that tomorrow this snake has a very bad life threating infection, would you STILL agree that what he did was right in HOW he did it ( I am NOT arguing that the snake should not have been saved, just saved by a qualified vet)?
Please keep us updated on your snakes progress and please post pics as well of your sutures on him/her.
