Eucalyptus, with its distinctive aroma and various uses, is a popular plant that finds its way into many homes. However, when you share your space with a feline friend, it’s crucial to consider the safety of your pet. In this article, we’ll explore the potential risks and precautions associated with eucalyptus and its essential oils when it comes to the well-being of your beloved cats.

Eucalyptus and Cats: The Concerns:

Eucalyptus is renowned for its aromatic leaves and the essential oils derived from them. While these oils have several benefits for humans, they can pose specific risks to cats:

  1. Toxic Compounds: Eucalyptus essential oils contain compounds like cineole and phenol, which can be toxic to cats when ingested or exposed to their skin.
  2. Respiratory Distress: The strong scent of eucalyptus can be overpowering for cats, potentially causing respiratory distress, sneezing, coughing, or nasal discharge.
  3. Gastrointestinal Upset: Ingesting eucalyptus leaves or essential oils can lead to digestive issues in cats, including vomiting and diarrhea.

The Toxicity Factor:

Eucalyptus toxicity in cats can vary depending on the form and concentration of the eucalyptus product. Here’s what you should know:

  1. Eucalyptus Leaves: While a small nibble on a eucalyptus leaf may not lead to severe harm, it’s best to prevent your cat from ingesting any part of the plant.
  2. Eucalyptus Essential Oil: Never apply eucalyptus essential oil directly to your cat’s skin or allow them to ingest it. Even a small amount of undiluted oil can be toxic and cause adverse reactions.

Precautions for Cat Owners:

  1. Secure Eucalyptus Plants: If you have eucalyptus plants at home, keep them out of reach of your cat, ensuring that they cannot nibble on the leaves.
  2. Store Essential Oils Safely: Store eucalyptus essential oils and products containing eucalyptus safely in a place where your cat cannot access them.
  3. Monitor Diffusers: Be cautious when using eucalyptus essential oil in diffusers or humidifiers, as the dispersal of the scent can affect your cat’s respiratory system. Ensure that your cat has access to well-ventilated areas.


While eucalyptus offers various benefits for humans, it’s essential to consider the potential risks it poses to your feline companion. Eucalyptus leaves, essential oils, and products should be used with extreme caution around cats to prevent toxicity and adverse reactions. Always prioritize your cat’s safety and well-being by keeping eucalyptus out of their reach and avoiding the use of eucalyptus products in their vicinity. If you suspect that your cat has ingested eucalyptus or is experiencing any adverse effects, consult your veterinarian promptly for guidance and care.
