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

[Cazador]

I froze my pinkies, up until eyes were opened. This is because they are cold blooded similar to herps until the eyes open.

Just to be clear, I think Kitkat was speaking figuratively since all mammals are warm blooded (endothermic). Small organisms have more surface area (skin) per unit of mass (volume), so they gain or lose heat more rapidly (like reptiles) than larger individuals do. Pinkies also lack hair and have minimal fat, so they have less insulation. This allows them to die and freeze quickly.

I won't offer an opinion on the most humane way to kill them because I think it's debatable and largely a matter of personal preference.
