Is Hoya heuschkeliana toxic to cats?

No — hoya heuschkeliana 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 heuschkeliana is not individually listed in the ASPCA toxic/non-toxic plant database, but the Hoya genus is clean: ASPCA lists Hoya kerrii (Sweetheart Hoya) and Hoya carnosa (Wax Plant) as non-toxic to cats, dogs, and horses, with no toxic Hoya members. It is therefore considered pet-safe; as always, verify with your vet, since any plant material can cause mild stomach upset if eaten in quantity.

Yes — the ASPCA lists hoya heuschkeliana 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 heuschkeliana is non-toxic to dogs as well. See the full hoya heuschkeliana pet-safety guide for both species.
