Carbon Monoxide Poisoning in Cats: A Hidden Danger at Home

In this guide

Carbon monoxide is easy to overlook precisely because it cannot be seen or smelled, and Indian homes have several everyday sources of it that owners rarely think about as a pet hazard.

Common sources in Indian homes

• Gas geysers, particularly older models installed in poorly ventilated bathrooms
• Generators run indoors or in an attached garage during power cuts
• Charcoal or coal used for barbecues or traditional cooking in an enclosed space
• Gas stoves and heaters used in a closed room, especially during winter
• Blocked or poorly maintained chimneys and exhaust vents
• Vehicles left running in an attached or enclosed garage

Why cats are especially vulnerable

Cats are often smaller than the humans in the household and tend to seek out warm, enclosed spots, such as near a running heater or in a garage, which are exactly the locations where carbon monoxide accumulates. Their faster metabolism and smaller body size also mean they can be affected more quickly than an adult human in the same room.

Symptoms of carbon monoxide poisoning

• Lethargy and weakness
• Disorientation or stumbling
• Vomiting
• Bright red or cherry coloured gums, which can be misleadingly mistaken for a sign of health
• Difficulty breathing
• Collapse and, in severe cases, seizures or death

What to do

If you suspect carbon monoxide exposure, move your cat to fresh air immediately and ventilate the affected area by opening doors and windows. This is a genuine emergency even if your cat initially seems only mildly unwell, since the gas continues to affect the body's ability to carry oxygen after exposure has ended. Get to a veterinarian promptly, as oxygen therapy significantly improves the outcome.

Prevention is more reliable than treatment here. Install a carbon monoxide detector in homes using gas geysers or heaters, never run a generator indoors or in an attached garage, and ensure any room with a gas appliance has adequate ventilation, particularly during winter when doors and windows tend to stay closed.
