Is Calendula toxic to cats?

No — calendula is listed by the ASPCA as non-toxic to cats. It is a sensible choice for a home with a cat; a curious nibble will not poison them, though no plant is meant to be eaten. Calendula officinalis (pot marigold / garden marigold) is listed by botanical name in the ASPCA database as non-toxic to both dogs and cats, with no toxic principles. Do not confuse it with the common bedding "marigolds" of the genus Tagetes (French/African marigold), which are a different genus that Pet Poison Helpline notes can cause mild gastrointestinal or skin irritation from the sap. Because they share the "marigold" common name but differ in toxicity, always confirm the botanical name before assuming a given marigold is pet-safe.

Yes — the ASPCA lists calendula as non-toxic to cats and dogs. A cat that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.

The ASPCA classification Growli uses applies to both cats and dogs: Calendula is non-toxic to dogs as well. See the full calendula pet-safety guide for both species.
