Is Sweet sultan toxic to cats?

No — sweet sultan 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. Centaurea moschata is not individually listed by the ASPCA. However, Centaurea cyanus (the closely related cornflower) is listed as non-toxic, and no toxic principles have been documented for this genus at typical exposure levels. Treat with appropriate caution, though serious toxicity is not expected.

Yes — the ASPCA lists sweet sultan 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: Sweet sultan is non-toxic to dogs as well. See the full sweet sultan pet-safety guide for both species.
