If not treated quickly, it can even cause death.Treatment generally consists of aggressive hospitalized care that includes inducing vomiting, administering activated charcoal, providing intravenous fluids, administering liver and GI protectants, as well as monitoring liver enzymes and blood clotting ability for a minimum of 48 hours.SucculentsLuckily, most succulents are considered non-toxic and are harmless to pets when ingested.
