Two of our igs (Reno and Paquita) were euthanized a couple years ago. No one had explained to me beforehand how the process really was (or at least, not to the point where I could feel emotionally prepared). I guess it's sort of inexplicable. Your iguana gets taken to another room for the injection, then handed back to you (very pissed off/confused, I might add), while you hold him/her for several minutes, as the breathing slows and he/she is no longer really able to move. I've been told it takes several hours to actually die, and there was no way I could be there for the duration. I can honestly say it's the hardest thing I've ever had to do, and it still messes me up when I think about it too much.
Drago was euthanized during surgery, and while that was its own set of mind-boggling thoughts, it was easier than straight up euthanizing in the exam room.
I hope for my sanity that Oggie passes away in her sleep.
I hadn't heard of the parietal eye injection. *shivers*
