I did a search of this forum on essential oils and it looks like pure essential oil is bad for a cat to be in contact with (via skin, or inhalation). I have a book on natural cleaning products. Some of the recipes (for example, floor cleaner) call for essential oils to be added. For example one recipe calls for 1 gallon of hot water, 2 tablespoons liquid castile soap, 10 drops pine essential oil and 5 drops cypress essential oil. This is to be mopped on floor and not rinsed. Would this be OK to use given that it is diluted so much? I read that peppermint, lemon, lavender, and tea tree essential oils are potentially toxic so I guess that would rule them out (even if diluted as above?). I would use this floor cleaner only in the kitchen- and probably not more than every 2 weeks. Any thoughts?
