Why are essential oils toxic to pets?

Essential oils should not be ingested in any form by our pets.

Cats lack the essential enzymes in their liver to metabolize and eliminate the chemical compounds in essential oils, therefore all essential oils have the potential to be toxic to cats.  Dogs do not have the same enzyme deficiency, but they can still be at risk of irritation or toxicity due to the concentrated nature of essential oils.

How to safely use essential oils around pets

To safely use essential oils around our pets, we first need to understand a bit more about how essential oils are most commonly used in our homes.

There are two broad categories of essential oil diffusers that you can buy, categorised as ‘active’ or ‘passive’ diffusers. Active diffusers emit particles of the oil into the air creating a light mist. These include humidifiers and vaporisers, glass nebulisers and ultrasonic diffusers. Be aware that the mist may land on furniture, bedding or your pet’s coat and be ingested while grooming.

Passive diffusers include reed or evaporative diffusers, candle or heat diffusers. They emit a less intense aromatic scent as there is no mechanism forcing the essential oil into the air. These are generally a safer option around the house with pets, however, we always recommend you chat with your vet prior to use.

Pets with existing respiratory conditions are at greater risk of developing respiratory distress. If your pet has any existing respiratory conditions, it is suggested to avoid the use of essential oils in your home.

With the increasing popularity of essential oil diffusers, remember these quick tips to keep your pets safe:

  • Always consult your Vet prior to use and follow label instructions
  • Avoid using oils in the same room as pets, and ensure all essential oil products are kept out of reach
  • Never leave your pet unattended around essential oil diffuser/vaporiser products
  • Source high quality and pure oils to avoid any potentially dangerous fillers

Signs of essential oil toxicity

One of the greatest risks of essential oils to cats and dogs is respiratory irritation. Respiratory irritation can present as:

  • Watery eyes and nose
  • Throat and nose irritation/burning
  • Nausea causing drooling and/or vomiting
  • Breathing difficulties shown by labored breathing, increased breathing rate, panting, coughing or wheezing.

Immediate treatment can be applied by moving your pet into fresh air, however if symptoms persist or you’re concerned, please consult your Vet as quickly as possible.
