Carbon Monoxide (CO) is a colorless, odorless, and tasteless poisonous gas that can be deadly when inhaled. It is often produced by malfunctioning appliances and poses a serious health risk in homes without proper detection.

Carbon monoxide can originate from various sources inside the home such as fireplaces, furnaces, gas appliances, vehicles, and portable generators. Being aware of these helps in effective prevention and detection.

More than half of pet owners are unaware of carbon monoxide poisoning symptoms in animals since signs are often vague. Recognizing these clues is vital for prompt action and protection of your pets’ health.
