Is Hoya Retusa toxic to cats?

No — hoya retusa 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 retusa is not individually listed by the ASPCA, but related Hoya species — 'Wax Plant' (Hoya carnosa) and 'Sweetheart Hoya' (Hoya kerrii) — are ASPCA non-toxic to cats and dogs, and no Hoya is on the toxic list, so it is regarded as pet-safe. As it is not individually listed, confirm with your vet if concerned; the milky sap may cause mild, temporary stomach upset.

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