How vets treat it

Call a veterinarian or Pet Poison Helpline immediately for life-saving treatment advice.

Why it's dangerous

High concentrations of the oil are rapidly absorbed through the skin or ingested, leading to central nervous system depression and potential liver damage.

Toxic compound: Melaleuca alternifolia oil

Good to know

Concentrations less than 1-2% are generally non-toxic; however, as little as 7 drops of 100% oil can cause severe poisoning.
