Harmless Beautiful Animals are being Euthanised every day, some counties in ohio even use Carbon Monoxide Gas Chambers: Delaware, Brown, Carroll, Fairfield, Holmes, Marion, Ottowa, Perry & Trumbell. Please sign this petition to stop the killing of Harmless animals because they can't find a home in 2 weeks. Could you? Ohio state law does not even regulate the use of this dangerous gas in shelters. Many states have banned its use and relatively few shelters in the U.S. still use this archaic, cruel method of killing animals.
