Are wax melts safe for cats?

While they are generally considered safe for humans, it's essential to be cautious when using wax melts around cats.

Some essential oils can be toxic to cats if ingested or inhaled in large quantities because your furry friend lacks the necessary liver enzymes to metabolise these oils. This makes them more sensitive to their effects.

Small amounts of essential oils might cause adverse reactions in cats, such as gastrointestinal upset, respiratory distress, or nervous system issues. With a heightened sense of smell compared to humans, certain scents can overwhelm or irritate your cat. Some cats may be more sensitive to strong fragrances, and exposure to heavily scented wax melts could cause respiratory issues or discomfort.

The wax melter can also pose a risk to cats. If a cat accidentally knocks over a wax warmer or comes into direct contact with the melted wax, it may burn itself.

Try to keep wax warmers out of reach of your cat's landing zone or in areas where they cannot be easily accessed.

Consider the following precautions:

1. Choose unscented or lightly scented wax melts: Opting for products with milder or no fragrances can reduce the risk of overwhelming your cat's sensitive nose.

2. Use in well-ventilated areas: Proper ventilation can help disperse any fragrance and minimise the concentration of scents in the air.

3. Keep wax warmers out of reach: Place wax warmers in areas your cat cannot access, such as high shelves or rooms off-limits to your pet.

4. Be aware of your cat's behaviour: If you notice any signs of discomfort, such as sneezing, coughing, excessive scratching, or changes in breathing patterns, discontinue the use of wax melts and consult your veterinarian.

Your cat is unique, and their reactions to scents will vary. Looking out for your cat's behaviour and well-being is a 'given'.

If you have concerns or specific questions about your cat's health, it's always best to consult a veterinarian for personalised advice.

Should we ask instead if cats are safe for wax melts?

Two types of wax melters are commonly used: tealight (naked flame) and electric. There is a good reason all the labels say, Never leave the burner unattended; anything can happen to it.

In one possible scenario, your furry friend can knock the melter and cause the tealight to set fire to a curtain or something similar.

Electric melters are safer because they only have a bulb. However, that bulb will get hot because it needs to melt the wax, which could have undesirable consequences in the wrong setting.
