Essential Oils and Pets: Cats & Dogs
Pets — cats especially, because they process certain compounds differently than we do — can be harmed by some essential oils through their skin, by licking them, or even from diffusing in a closed room.
Here is what to be careful with and how to diffuse safely. This is general guidance, not veterinary advice — always check with your vet.

Dilutio applies the safe dilution to every blend, flags phototoxic and pet/child/pregnancy cautions per oil, and exports a clean recipe — across a 225+ oil library. No MLM, no starter kits.

- Tea tree (melaleuca), eucalyptus, and camphor.
- Citrus oils (the d-limonene in them), peppermint, and pine.
- Wintergreen, cinnamon, clove, and pennyroyal.
- Cats are especially sensitive — when unsure, keep oils away from them entirely.
How to diffuse safely around pets
- Use short sessions in a well-ventilated room, and give pets a way to leave.
- Never apply essential oils directly to a pet, or add them to food or water.
- Keep bottles and diffusers out of reach.
- Watch for drooling, lethargy, wobbliness, or breathing changes — and contact your vet if you see them.
