What this means for your cat
Summer hyacinth (a Galtonia, not a true Hyacinthus) is on the ASPCA non-toxic plant list for cats. Note that ordinary spring hyacinth (Hyacinthus orientalis) IS toxic to cats — Galtonia is the look-alike that's safe. A cat chewing on a leaf or bulb scrap may briefly vomit from the plant fiber.

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.
