@chai2,
I agree it's sadistic and I would wonder about the mental state of a person who could actually do it.
I've posted this story before on similar threads, but it apparently bears repeating- it's about shooting your pet. I live near a farmer who has often put down animals, mostly for food or humane reasons. He had a favorite hunting dog that was very old and sick and he decided to put the dog out of it's misery by shooting it. Apparently just as he positioned the gun behind the dogs head and pulled the trigger the dog turned to look back at his owner. This caused the bullet to blow off a chunk of the dogs head but not kill it. The dog yelled in horrible pain before the man got off a second killing shot. He told me this tragedy has haunted him ever since and he no longer kills the animals he loves, but brings them to the vet to have it done humanely.
I know Kicky would never do anything cruel to his critters, but this is a very public place and you never know who might take some of these ideas seriously. Suggestions like rat poison, drowning and suffocating are evil and painful. The problem I see is some idiot might stumble on this thread and think some of these ideas might be worth trying.
