With the holiday season upon us, we want a warm and fragrant home.

Scented candles, incense, air freshener sprays, essential oil diffusers, and even electric plug-ins are making their appearance in our homes.

However, they can represent a real danger to our companions, especially cats, dogs, birds and small mammals...AND US!

Sensitivity varies from animal to animal, but four main factors influence the risk: the product's composition (essential oils, solvents, synthetic fragrances), the concentration in the air, the duration of exposure, and the animal's individual vulnerability. It's best to be aware of the effects to protect those who share our lives.

What are the main risks to animal health?

Irritations and respiratory problems
Animals' respiratory systems are far more sensitive than ours. Scented sprays, candle or incense smoke, and emissions from diffusers can cause coughing, sneezing, runny nose or eyes, and asthma attacks. Cats and small dogs, already prone to respiratory problems, are particularly vulnerable.

Humans too!

Systemic toxicity
Some volatile compounds cross the lung barrier and enter the bloodstream. The liver, kidneys, and nervous system then work to eliminate these substances. Cats are even more at risk because their bodies metabolize many essential oils very poorly.

Endocrine disruptions
Synthetic fragrances and certain phthalates found in air fresheners are suspected of acting as endocrine disruptors. Chronic exposure could contribute to hormonal and metabolic disorders (obesity, diabetes) or even certain cancers.

A closer look at the most problematic products

Essential oil diffusers
Highly concentrated, essential oils are far from harmless. Tea tree, eucalyptus, mint, citrus, and many others can be toxic to cats, and irritating or neurologically active in dogs and exotic animals. Their continuous diffusion into the air increases the risk of accumulation in the body.

Air freshener sprays and room fragrances
When sprayed into the air, they create a dense cloud that animals inhale directly. This acute exposure can cause coughing, respiratory distress, malaise, and allergic skin or digestive reactions if particles settle on the fur and are then licked.

Scented candles, incense and plug-ins
These products combine synthetic fragrances, fine particles, and sometimes smoke. Respiratory risks then become chronic, especially for cats, birds, and elderly animals.

How to recognize a reaction in your pet?

Respiratory signs
Coughing, rapid or noisy breathing, wheezing, mouth breathing (especially in cats), asthma-like attack.

Behavioral changes
Agitation, prostration, attempt to leave the room, rubbing of the muzzle or eyes, excessive licking.

Other symptoms
Vomiting, excessive salivation, tremors, disorientation: these signs appear mainly after exposure to highly concentrated products or accidental ingestion.

Best practices for a safer home

Ventilate regularly rather than masking odors with perfumes.

Avoid sprays and diffusers in rooms where animals spend the most time, especially if they are fragile (cats, birds, animals with heart conditions or asthma).

Never spray perfume near an animal, on its bedding, sleeping area, or cage. Avoid "pet perfumes" altogether.

If you still want a scented atmosphere, choose simple, very lightly scented products and use them sparingly, allowing the animal the option to leave the room.

If symptoms occur, immediately stop using the product, ventilate the area, remove the animal and consult a veterinarian with the product in question or a photo of its label.

In a home with pets, air fresheners should be used sparingly, sparingly, and never in areas where the dog or cat cannot escape. Good air quality is better than a pleasant but potentially harmful scent. Protecting the health of our companions begins with caution and the responsible use of these everyday products.
