This article uses the websites listed below in arguing the negative effects of lavender for cats. It states that while lavender is used for many aroma therapy calming properties for humans, for cats this is not the case. Due to the chemicals such as Linalool and Linalyl acetate within lavender it can, “irritate the skin, eyes, mucous membrane, and gastrointestinal tract in cats, along with potential liver damage” (Stregowski). Although not deadly upon ingestion or exposure, this plant can cause veterinary attention needed for cats due to its unhealthy components, deeming it unsafe for cats.
