Is Serpens Wax Plant toxic to cats?

Hoya serpens is not individually listed in the ASPCA database, but the Hoya genus is clean: ASPCA lists Hoya carnosa (wax plant) and Hoya kerrii (sweetheart hoya) as non-toxic to dogs and cats, with no Hoya species flagged as toxic. It is therefore considered pet-safe; still, verify with your vet, as nibbling any plant can cause mild stomach upset.
