Is Night-Blooming Cereus (Dragon Fruit Cactus) safe for cats and dogs?

Severity: Mild
Night-blooming cereus, also called the dragon fruit cactus, is a sprawling, climbing cactus known for its large white flowers that open only after dark and close by the following morning. The ASPCA lists Hylocereus undatus as non-toxic to both cats and dogs; the plant's only real hazard to a curious pet is physical, from its spines, not chemical.
This same species has also become a specialty American fruit crop. In Southern California, University of California Cooperative Extension advisors in San Diego County have run an annual Pitahaya/Dragon Fruit Production Tour since 2007, connecting home growers with commercial operations such as a 20-acre farm in Moorpark that has grown dragon fruit for about 20 years. In Florida, UF/IFAS describes pitaya as "an emerging crop in south Florida," with production concentrated around Miami-Dade County and acreage that "has grown rapidly" as growers explore it as a commercial option.
For pet owners, the takeaway is simple: whether it's grown as a flowering houseplant or a fruiting vine on a trellis, night-blooming cereus/dragon fruit cactus won't poison a cat or dog that chews on it — just keep paws away from the spines.
