Is Threeleaf Arrowhead toxic to cats?

No — threeleaf arrowhead 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. Sagittaria species (aquatic arrowheads) are not listed on the ASPCA toxic plant database and are widely regarded as non-toxic. The starchy corms are an important edible food crop across Asia, further supporting the non-toxic classification. Note: 'arrowhead vine' toxicity records refer to Syngonium podophyllum, a completely different genus.

Yes — the ASPCA lists threeleaf arrowhead 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.
