lifted off facebook - it also applies to parrots..... (not me- someone elses cat) This is my daughter's cat, Ernie. He has lived with us most of his 16 years. I unknowingly have been poisioning him since Christmas and feel the need to warn everyone who might be unaware of the toxicity of essential oils. I bought a diffuser and a set of essential oils from Amazon. I gave it to my husband as a gift and also one to my daughter and daughter-in-law. We started using ours soon after the holiday and loved how the different oils made the house smell, trying a different one each day. I came down with a head cold. On the package with the oils, it said that eucalyptus oil was good for congestion, so we had the diffuser going several hours for several days in a row and close to where I was sleeping. Ernie loves sleeping with me. The first couple days I didn't notice any symptoms with Ernie, but on the fourth day, he was lethargic, unstable on his feet and was drooling excessively. My husband instinctively Googled eucalyptus oil. It stated that it can be toxic to cats and they can't metabolize it and stated all of Ernie's symptoms. It also said that without medical attention, it could be fatal! So I took him to the Vet right away! The Vet gave him a shot of antibiotics and another shot of vitamins to boost him and instructions to watch him over the weekend. Ernie hasn't been himself. He is eating and drinking a little, walking a little better, has some diarrhea, but is still not out of the woods. We also learned that out of the 8 oils in our set, only 2 are NOT toxic. Rosemary and Frankincense. Orange, Lemon, Tea Tree, Eucalyptus and Lavender ARE toxic to cats and small animals. There is no warning anywhere on these essential oils, which I feel is shocking! We have also learned that the candles we love to burn are scented with essential oils. Sorry this post is so long, but if this helps to keep any of your animals safe, it was worth the rant!!!
