PETITION TARGET: Green River Mayor Pete Rust

UPDATE (2/21/2022): Green River Mayor Pete Rust told Lady Freethinker that the city’s governing body has voted in favor of replacing the inhumane gas chamber with a more humane injection option.

“On January 4th the governing body of Green River began the process of  ‘transitioning’ away from the use of the gas chamber towards the injection method for euthanizing animals where necessary, by directing staff to explore various facets related to this transition such as staffing, aid from local Veterinarians as well as of course any needed training and equipment and do so ‘in a timely manner’,” he said.

But City Administrator Reed Clevenger said there is no timeline to finalize the transition, that staff were consulting with veterinarians, and that the city would have to look at the situation “from a budget perspective,” according to the Rocket Miner.

“In the meantime, we will be implementing an immediate stop to all gas chamber euthanasia and send out the animals accordingly if the equipment they have or the veterinarian partnerships we have cannot accommodate our needs,” he said.

While this is a positive development, we will keep watching this case to make sure the changes are implemented.–Lady Freethinker Staff


The horrors for an unsuspecting dog forced into a gas chamber start with the loud and frightening noise of deadly gas.  Then come muscle spasms, as coordination fails. Convulsions are common during the excruciating and painfully prolonged process that follows — with studies recording heartbeats for up to 20 minutes after animals are exposed to carbon monoxide.

Death by gas chamber has been deemed so inhumane that the cruel practice is only legally allowed in animal shelters in four states — and most of those states have no existing chambers, although the laws are still in the books.

But Green River Animal Control, in Wyoming, is still operating a brutal carbon monoxide gas chamberand it is high time they replace this cruel killing machine.

Carbon monoxide poisoning can cause significant distress to animals, cannot be relied on to deliver a rapid or even certain death, poses significant physical health risks for shelter staff, and is a more expensive method than euthanasia by injection (EBI).

Sign our petition urging Green River Mayor Pete Rust and the City Council to outlaw the use of any cruel gas chambers within his jurisdiction and to transition to humane methods for euthanizing animals.
