This is a way of sending poor unwanted or sick animals across the bridge that is boarder line "Animal Cruelty". This needs to be stopped. The animals suffer on their way out of this hateful world. Before they pass, they suffer threw 40 minutes of shear terror, anxiety, fearfulness, and some, honestly, I wonder if aren't scared to death in the process. This is totally wrong and against the laws of nature so why not laws of our states. This law should be directed at the shelters using this technique of punishment. Louisiana is still using this. Vermillion Perish being one in particular. Please help me in helping the fight against this abuse of gassing by not just making it illegal to send animals to a dumpster by this process, but make it illegal to even make the devices used to carry out such a terrible crime of nature.
