If anyone owns a cat it may be worth heeding the following advice. I came across an article regarding this matter.
Apparently Essential oils can be toxic to cats, whether taken internally, applied to the skin, or simply inhaled.
The liver is most often the organ which is affected by essential oils. Cats' livers are simply not the same as humans' livers, and they lack the ability to properly metabolize the various compounds in essential oils.
Toxicity in cats can occur very quickly, through internal or external application, or over a longer period of time, through repeated or continuous inhalation of essential oils, but either way, it can lead to serious liver damage or even death.
