Is Hoya caudata (Sumatra) toxic to cats?

No — hoya caudata (sumatra) 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. Hoya caudata is not individually listed by the ASPCA, but the Hoya genus is clean: the ASPCA lists Wax Plant (Hoya carnosa) and Sweetheart Hoya (Hoya kerrii) as non-toxic to cats and dogs, with no Hoya listed as toxic. It is therefore considered pet-safe; eating any plant can still cause mild stomach upset, so verify with your vet if concerned.

Yes — the ASPCA lists hoya caudata (sumatra) 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: Hoya caudata (Sumatra) is non-toxic to dogs as well. See the full hoya caudata (sumatra) pet-safety guide for both species.
