Severity: Mild
The Yucca genus this record covers is not only a nursery import in California - Mojave yucca (Yucca schidigera) is a true California native. A fact sheet from the University of California's Riverside County Master Gardeners states plainly that it is "native to southern California," growing in coastal sage scrub near the coast, mountain chaparral, and desert transition zones from sea level up to 8,200 feet, with its overall range spanning the Mojave and Sonoran deserts of southeastern California, Baja California, southern Nevada, and western Arizona. That means the "Yucca species" a cat or dog might chew on in California ranges from an ornamental planted at a nursery-bought entryway to a genuinely wild desert plant encountered off-leash on a Southern California trail.
ASPCA's genus-level entry for Yucca spp. lists it as toxic to dogs and cats, with saponins as the toxic principle and vomiting as the documented sign in both species (liver disease and dermatitis are listed separately for horses). Saponin exposure is usually a stomach-upset problem rather than an emergency, but a pet that will not stop vomiting after chewing on a yucca's sharp-tipped leaves should still be seen by a veterinarian.
