i read on the "new scientist" magazine that using CO2 (as in using dry-ice) to kill animals was once thought to be painless but in fact gives the animal "a distinct sensation of being suffocated" because animals have sensors about CO2 levels or something... cant really remember... the new method that they are trying to put into practice is using nitrogen.... but seeing as we can't get hold of that, using carbon monoxide?

ps. there was also this interesting article about how all colubrids, which where once thought to be non-venomous, are in fact venomous. that snakes did not evolve venom (they had it when they evolved from venomous lizards), but boas/pythons evolved out of having/using venom. you guys ever heard of anything similar?
