The details of euthanasia are hard to read but understanding the process is the first step to improving it nationwide.  As you can imagine, gassed animals claw, cough, choke and struggle until they become unconscious. 

Luckily, Florida is one of the twelve states that have banned the antiquated chambers into which homeless animals are herded and asphyxiated with lethal gas.  Six more states are currently considering legislation pending to ban the chambers.  Sadly, that still leaves 32 states using hundreds of the chambers.

It can take anywhere from 20 to 45 minutes for animals to die in gas chambers. Oftentimes, they bark, meow, howl, whine, gasp for breath, fight to claw their way out of the chamber, vomit, convulse, and/or urinate and defecate in terror. Animals sometimes have to be gassed repeatedly before they die.
Cost issues favor the injections with the average cost of one injection to be $2.29 while the average cost of one gassed animal comes out to $4.98, as well as high up-front costs for the equipment.
We the undersigned ask you to BAN gas chambers in All US States. And Introduce Humane Death Laws Implemented in ALL States Of The USA.
Thank You for your Co-operation
