In a home that runs a diffuser, an air freshener or essential oils, the first thing to read is the ingredient list on the label. Pick the fragrances or oils you found there and this checker reports only whether they match a list of oils with reported risk. It never returns a verdict that a product may be used, and it supplies no usable concentration or dilution ratio.
The list is taken from the essential-oil toxicosis entry in the Merck Veterinary Manual and from cases reported by the ASPCA, and is current as of October 2026. Cats lack glucuronyl transferase, so phenols and phenolic compounds are not cleared and accumulate in the body. That is why the exposure cannot be managed by using less, and why removing a matched product is the whole answer.
This tool does not cover product-specific content, diffuser run time, toxic doses or treatment. A result of no match only means no reference confirmed that ingredient. It is for reference only and does not replace veterinary care. Contact your veterinarian right away if you see drooling, tremors, wobbliness, vomiting or labored breathing.
