How exactly does one "practice" euthanasia? I mean, does that mean that one is practicing for some goal, for some big test on it? Snowflake, the only known albino gorilla in captivity, was put down after they noticed that he showed signs of pain for 4 or 5 days. Honestly, does no one see the problem here? But back to my question, why the hell do they call it practicing? What's the final goal here?
