Lavender is not safe for cats, after reading this source carefully and following its data points, I have found that this claim is a true statement. Lavender is found to have really harsh chemicals, including linalool and linalyl acetate, which can harm cats' livers. In this article, they cite evidence from the ASPCA, and after researching this website, I found that this is a very well-researched position control center. I also found from both websites that cats can be exposed to the lavender plant, but under no circumstances can they eat it. Cats are not very likely to die, but they will be in serious harm. This source is filled with a lot of good information and has clearly valid sources. This sources claims to be "vet reviewd and pet approved" which is another valid form of verification. Since they clearly have the same information as the poison control center, this website information is valid.
