Snake Plant

ASPCA lists Snake Plant (Sansevieria trifasciata) as Toxic to Dogs and Toxic to Cats: species-level/common-name match, no naming-trap concerns. Toxic principle: saponins. ASPCA's clinical signs are mild/GI-only: nausea, vomiting, diarrhea: same low-severity group with gardenia and lavender, not the cardiac-risk group named for azalea. NC State's independent listing adds detail ASPCA's page does not include: occasional blood in vomit, depression, anorexia, hypersalivation, and dilated pupils specifically in cats, plus a note that the sap itself can cause skin irritation on contact, and that all plant parts (not just leaves) are considered poisonous. ASPCA's page does not address horses for this species (only dogs and cats are listed), unlike some other plants in PlotAndPetal; NC State separately names horses and children among those at risk, which is worth treating as supplementary information since it isn't the ASPCA companion-animal verdict.
