Eucalyptus is a plant recognized worldwide both for its cosmetic uses and its medicinal properties.

Specifically, in the medical field, its powers as a nasal and respiratory decongestant are well recognized. In some nations, it is even used to manufacture chemical products, as a potent insect repellent and in Australia, it is associated as the main food source of the tender koalas.

Oh, and it’s also famous for smelling like urine… Wait, what?

Does Eucalyptus Smell Like Cat Pee?

Eucalyptus does not smell like cat pee. The smell of eucalyptus is perceived as very intense but also fresh, with hints of woody and menthol.

Still, many people find its scent similar to the smell of cat urine. It is a crazy comparison although we must remember that every nose is different.  There is no scientific explanation behind this strange phenomenon. I guess it’s a matter of smelling the eucalyptus and trying your luck. 

If there is one thing that most people who have smelled eucalyptus agree on, it is that in large quantities it can be too heavy and annoying.

What Is The Relationship Between Eucalyptus And Cats?

It is quite curious that the stong smell of eucalyptus is related to cats when they hate this plant and avoid it at all costs.

For the most part, cats reject the aromas of certain plants that are toxic to their sense of smell. A very particular case is the hatred they feel towards eucalyptus since the essential oils of this plant can be harmful to the animal’s health. It is simply a survival instinct.

For this reason, many cat owners use a small amount of eucalyptus to keep their pets from urinating in certain areas of the house.
