Maine –
“A family in Cushing, Maine, says their Maine Coon cat may have saved their lives after her strange cries drew attention to a dangerous carbon monoxide problem in their home.
Her behavior gave William and Pat Aboud enough warning to get outside and call for emergency help…Responders discovered hazardous carbon monoxide levels in the house and traced them to a faulty propane furnace in the basement. William was later flown by LifeFlight to Boston’s Massachusetts General, where he received two-and-a-half hours of hyperbaric treatment…
Make sure your home has working carbon monoxide detectors, especially near sleeping areas…”
