Is Hoya macrophylla toxic to cats?

No — hoya macrophylla 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 macrophylla is not individually listed in the ASPCA toxic/non-toxic plant database, but the Hoya genus is treated as clean: ASPCA lists Hoya kerrii (Sweetheart Hoya) and Hoya carnosa (Wax Plant) as non-toxic to dogs, cats and horses, with no Hoya listed as toxic. It is considered pet-safe; as with any plant, ingestion can still cause mild stomach upset, so verify with your vet if your pet has sensitivities.

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