OK i got a question. how is it these mice die if done properly with c02 aint they still suffocated? i mean you take the oxygen away whether awake or asleep. they are still suffocated to death. no way you word you took there oxygen away right? so you suffocated them to death

lil info about c02 concentrations and the effects it has before death occures
# 1% can cause drowsiness with prolonged exposure.[5]
# At 2% it is mildly narcotic and causes increased blood pressure and pulse rate, and causes reduced hearing.[47]
# At about 5% it causes stimulation of the respiratory center, dizziness, confusion and difficulty in breathing accompanied by headache and shortness of breath.[47]. Panic attacks may also occur at this concentration.[49][50]
# At about 8% it causes headache, sweating, dim vision, tremor and loss of consciousness after exposure for between five and ten minutes.

link this info came from
http://en.wikipedia.org/wiki/Carbon_dioxide

OK so from this we can see it takes prolonger exposure for any of the results even death which they said in other section is around 10%. OK so look at what happens before 10% notice loss of consciousness dont occur till 8%. at 5% adverse side effects start to occur in the forms of dizziness confusion panic attacks difficulty in breathing. (if that happened to you wouldn't you be calling a doctor to be seen asap i know i would be) then at 8% before going to sleep we see it cuases headaches sweating then vision dims then loss of consciousness. then 10% is reached and after a few minute dies. i dont know the stuff that happens before loosing consciousness don't sound that humane to me (my personal opinion)

yeah that sounds humane to me now that i read that is all that is happening to them. cause hey one of the first effects is narcotic so they think they are happy.

my whole point of arguing this topic is suffocation is suffocation. and is suffocation considered humane? no by no means is suffocation considered humane. your just choosing to use it cause other people say it is cause supposedly the prey falls asleep before they die or suffer any but from the info i posted shows there is stuff happening that would make anything try to get away first. just cause the prey can't speak up and say hey get me out of hear or hey what happening to me don't make it humane. so with that reasoning why not just smack a sleeping mouse in the back of the head to kill it its asleep it wont feel it right its asleep just like using c02 to cuase an animal to suffer before it dies. (by suffering i mean it has panic attacks, headaches, difficulty in breathing, shortness of breath, tremors, dizziness, confusion)
