Is Shingle Plant Hoya toxic to cats?

No — shingle plant hoya 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 imbricata is not individually listed in the ASPCA's plant database, but the genus is treated as clean: the ASPCA lists Hoya kerrii (Sweetheart Hoya) and Hoya carnosa (Wax Plant) as non-toxic to dogs, cats and horses, with no Hoya species listed as toxic, so it is considered pet-safe — verify with your vet if unsure. The ASPCA files Hoya under the older family name Asclepiadaceae (modern taxonomy places it in Apocynaceae). As with all hoyas, cut stems can exude a milky latex sap that may mildly irritate the mouth or cause minor stomach upset if a pet chews a large amount.

Yes — the ASPCA lists shingle plant hoya 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: Shingle Plant Hoya is non-toxic to dogs as well. See the full shingle plant hoya pet-safety guide for both species.
