    The mice I get are thrown against a wall as far as I know
    Does your water bowl look like a toilet, it does? Guess I will have to change it again

    Re: freezing mice......humane question...well lots of

    I would rather pay a little more to kill them quickly and humanely..
    If I set the C02 up, maybe just wait until they were older than 10 days...
    And hire someone else to actually put them into the chamber and turn on the gas....(don't think I could throw them at anything or even flick them for that matter!!)
    As I am a bit too soft maybe I will just keep paying through the nose for frozen mice! let someone else have it on thier mind....it was just a thought

    Hey I don't blame you one bit. I used to do the nose flick and such. Even used to snap bunny necks with my hands if needed, while I was working at the pet store. Counldn't do that now though.....I don't feed anything alive, unless it's crickets or mealworms (even cockroaches get to me....I had some as pets!). Yeh, I'd rather let someone else worry about doing in my mice....and I'll just hope it was done well.

    Re: freezing mice......humane question...well lots of

    Hi all,
    I just wanted to sort of discourage the carbon monoxide (CO) idea because it has a really high affinity for the iron molecule in hemoglobin, and essentially binds irreversibly. That means the CO will remain in a red blood cell until the cell dies, and they normally have an approximately 60 day lifespan. Even if all the red blood cells ruptured during freezing, the lack of a functional circulatory system would prevent its release from within the mouse. There is also the distinct possibility that you might euthanize yourself while administering the CO to the mouse. Keep it safe,
    Rick

    Feel free to correct me:

    The impression I got from last week's chemistry class (I study sustainable development and the course is very ecology/biology oriented, so much of the focus has been on carbon and oxygen), the body uses iron (certain animals use copper) in hemoglobin to bind and transport oxygen and CO is attracted to that oxygen. The reason is that CO is unstable and by attaching itself to that O, it creates CO2 and becomes stable. It doesn't stay CO, it becomes CO2 in the body. Disclaimer: it wouldn't surprise me if this explanation was wrong, I wouldn't expect a chemistry teacher to know the first thing about biology. Most explanations suggest that CO just replaces the O in the protein and none of them seem to consider it a direct health hazard when consumed (as opposed to inhaled). According to wikipedia CO is even used to treat seafood and beef?

    Woah, Rick, You're just too smart for me. So, if you use Carbon Monoxide, then you freeze it, and your snake eats it, it will get poisoned?

    Re: freezing mice......humane question...well lots of

    Yep, I think thats what hes saying..
    C02 is a pure gas, the body makes it anyway..
    But Carbon Monoxide (as in car fumes) is extremely poisonous!
