📖About Can Cats Eat Rosemary?
Rosemary is listed as non-toxic to cats by the ASPCA, and a small accidental nibble is unlikely to cause harm. The herb contains antioxidants and has anti-inflammatory properties. However, cats should not be given rosemary regularly or in significant amounts. Cats are particularly sensitive to the essential oils found in herbs, including the volatile oils in rosemary. While the fresh herb in tiny amounts is generally safe, concentrated rosemary oil or extract can cause gastrointestinal upset, depression, and in severe cases, liver toxicity in cats. Cats lack the glucuronyl transferase enzyme that helps metabolize many plant compounds, making them more vulnerable to herb toxicity than dogs or humans. Rosemary is sometimes included in small amounts in commercial cat food formulations as a natural preservative, and this processed form is generally considered safe because the concentrations are carefully controlled. If your cat nibbles on a rosemary plant in the garden or kitchen, there is typically no cause for alarm. However, do not purposefully feed rosemary to your cat or use rosemary essential oil in any form around cats. For cats with epilepsy, rosemary should be strictly avoided as it may affect seizure thresholds.
