I had heard about that one Australian guy who made that euthanasia machine, so I decided to look it up. One of the sites I came across had very detailed instructions about how to euthanize your pet at home. I almost threw up! That was so sickening! How could anyone euthanize their pet at home, without the supervision of a vet!? This is so disgusting! Any moron could kill an animal with those horrible instructions. I can't believe something like that was on the internet. I just had to rant about that. It was so disgusting.
