About the Co2 thing! I thought of it as it is similiar to when ppl kill themselves in garage w their car.... I thought they dozed off.
FYI: death from carbon dioxide poisoning is not pleasant. It is suffocation, and the animal is very aware. When people kill themselves by running the car in the garage, it is carbon monoxide poisoning, and they, as you say, simply doze off. Many people die each year when their furnace malfunctions and produces CO (Not CO2). They just never wake up. So, I don't think CO2 is a humane way to 'euthanize' animals.
Yeah, you're probably right! If they were my bunnies, I'd do the broomstick method and my chickens I'd do whatever was fastest. But, hey, I'm pretty sure it's CONSIDERABLY more humane than any treatment the animals in dog food (or even the store for that matter) have ever seen. I'm all about feeding and eating animals who saw daylight, had adequate living space, ate the proper diet, and were well-cared for... so that outweighs the maybe not as pleasant as it should be death. When you buy meat from the store or support the kibble industries (most of them, granted, not all) you're supporting some really evil practices. Horrendous acts of animal abuse.
In the future, should I buy live animals, I'd kill them the quickest way. Not everybody has the guts to do that, though, so I am not angry with said company, I'm just thankful they gave them such a great life during the time they were here and that I have such healthy animals to feed my gang.
