Sweetheart hoya
Hoya kerrii
Sweetheart hoya is non-toxic to cats. Its heart-shaped leaves make a lovely addition to a cat-friendly room, but keep the vines away from determined nibblers.
Non-toxic does not mean edible. Eating plant material can still upset your cat’s stomach.
What this guide covers: Hoya kerrii only. Check the botanical name; a photograph alone cannot establish identity.
