There are certain ways of euthanizing an animal that are less cruel than others. Sticking them, alive, into a freezer or cooking them alive/drowning them is not one of them. (You shouldn't feed a cooked mouse to your snake, anyway.)
I'm beginning to see though that this is all a joke to you. I am starting to wonder if you even have a left over mouse or not? If you're just trying to get a rise out of people or what?
You asked for and received advice and you seem intent to lash out or fight back against at those trying to help you. Why bother posting in the first place if you are so determined and your mind is made up? That's what I would like to know.
Unfortunately this post was not a joke and I have gotten rid of the mouse. I won't even go into details seeing as youare getting so flustered.
