This is a question that I receive a lot. And, it's an important one!
If your pet has health issues or you have concerns, always err on the side of caution. Speak with your veterinarian if you have questions about a particular health issue.
Speaking generally, now, bear in mind that our fuzzy friends are scent-sensitive. That can be a great thing, but it may mean that they don’t want to be in the room where you’re diffusing. Always allow them the freedom to remove themselves from the area. Also, don’t leave your diffuser running for hours at a time. Don’t allow aromatic vapours to build-up ~ always have good ventilation when you’re diffusing around pets.
So, this begs the question, ‘Are there specific oils that are toxic to pets?’ In this post, I’m only speaking about diffusion ~ not topical application (that’s a different issue). If you keep the above-mentioned points in mind, diffusion around cats and dogs is not usually a concern. But, if you feel that your pet is extra-sensitive, just avoid diffusing around them. If you’d like to enjoy your blend without Rover nearby, send him out to the yard to play, or enjoy your blend while a family-member takes him for a walk.
You are your pet’s best advocate. Be aware if he/she leaves the room while you’re diffusing. If you see a behaviour that concerns you, you can avoid that oil or blend and try a different one. Essential oils are chemical compounds and they can be vastly different in their makeup.
