Live animals used in keychains

[Catherine]

It seems that in China you can buy a keychain with a live animal trapped inside it. Mostly they die in a few days when their oxygen runs out. It seems particularly cruel to take a baby animal and seal it in plastic and let it die slowly. They struggle to escape, but escape is not possible. They are essentially entombed while still alive.
Who sells such things and who buys such things? Who thought this up?

Is there no end to the new ways we come up with to be cruel to animals?
