I recently read that Lavender oil can be toxic to cats, even if it's just inhaled. I regularly use a diffuser in my bedroom. My cat doesn't seem to have any negative reaction to it though. But some articles have said that it takes time for the toxins
It really depends on the product and the concentration. The fact that it is organic would not necessarily make a difference in the potential for problems. The truth is that there is little known about the safety of these products, because the companies have not adequately tested their products with animals. There are some essential oil diffusers like lavender that have been known to cause respiratory and skin problems. In general, dogs and cats are going to be more sensitive to the smell of these products than humans, so it may be at-least displeasing to them. Cats are more sensitive than dogs, so they will likely serve as the sentinel if there are going to be any issues. If you are already using the oils and not noticing any problems, then they are likely OK; but no one really knows for sure. If you notice an increase in sneezing, coughing, or skin problems, then it would be wise to remove the diffuser. I hope that helps and all is well with Shyanne.
