Is Hoya lacunosa toxic to cats?

No — hoya lacunosa 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 lacunosa is not individually listed in the ASPCA toxic/non-toxic plant database; however, the genus is clean — ASPCA lists Hoya carnosa (Wax Plant) and Hoya kerrii (Sweetheart Hoya) as non-toxic to dogs, cats and horses, with no Hoya species listed as toxic. Treated as pet-safe, but eating large amounts of any plant can cause mild GI upset, so verify with your vet if your pet is sensitive.

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