Common questions

Why is rosemary extract in cat food?

The extract is used as a natural antioxidant preservative and is recognized as safe in the tiny quantities used.

Can rosemary essential oil hurt my cat?

Is a rosemary plant safe to keep indoors?

Yes. The potted herb is one of the safer kitchen-window plants for cat households.
