Essential oils are concentrated plant extracts known for their aromatic and therapeutic properties.
They’re commonly used to add pleasant scents to our homes and are found in a variety of products including, toiletries, cosmetics, diffusers and plugins. Essential oils are also used in aromatherapy, which is using oils for therapeutic benefits.
While essential oils can make your home smell inviting, many are toxic to cats.
Read on to discover which essential oils are most harmful and learn best practices for using them safely in your home.
Toxic essential oils
Most essential oils are toxic to cats. Harmful toxins can be exposed to our felines through skin contact, ingestion, or inhalation. Oils are especially dangerous when used neat (undiluted). While household products often contain diluted oils, cats are still highly sensitive and exposure, even in small amounts, can be harmful.
Symptoms of essential oil poisoning
Cats are sensitive to essential oils, even in small amounts, because they lack certain liver enzymes needed to break down the compounds found in these oils. Exposure can lead to organ damage – including liver failure, seizures, and in severe cases, death.
Extra care should be taken around cats with underlying health conditions such as, asthma as they are at greater risk.
Symptoms of essential oil poisoning may include:
- Excessive dribbling
- Tremors or shaking
- Becoming unsteady on their paws
- Lethargy
- Difficulty breathing – they may also breath with their mouth open
- Vomiting
- Seizures
- Collapsing
If your cat displays any of the symptoms, seek veterinary attention immediately. Owners concerned their pet has been poisoned can also ring APL (Animal Poison Helpline) on 01202 509000 for advice, this is a 24-hour service.
Keeping your cat safe
While essential oils can be harmful, there are safer ways you can use essential oils around your feline friends. We should be mindful of what oils we are using and take precautions to prevent your cat from coming into direct contact with them.
Tips for safer use
- Store out of reach.
- Wash your hands after handling
- Only use heavily diluted oils.
- Avoid cleaning with essential oils
- If used in cleaning, ensure surfaces are dry before contact.
- Keep oils away from areas where your cat eat, sleeps and plays
- Keep cats out of rooms with diffusers or plug-ins.
- Ventilate the area well before letting your cat enter.
- Use only vet approved flea products – some over the counter flea treatments contain essential oils. We recommend always getting your flea treatment from a vet or pharmacy.
No essential oil is completely safe for cats. For calming or scent alternatives, choose veterinary approved products, such as, Feliway and Pet Remedy.
When in doubt, always prioritise your cat’s safety – a fresh smelling home is never worth risking their health.
