My son ended up in the local jail for driving on a suspended licence, and was assigned work at the local animal shelter. What he saw and heard horrified him. There were several long term inmates that worked there and they told him what they had witnessed. One was that they did not give enough sedative to the animals, so that when they threw them in the gas chamber they were fully conscious. Two, was what he witnessed as well, was a couple skinning the animals afterwards. He was told that the skins were sold, and the meat went to producers of dog and cat food. He also saw that the road kills were added to the hides and the meat sold. He didn't know if they were just telling stories, but made it a point to witness himself what was going on, and confirmed they were not just telling stories.
