Frequently asked questions
- Are snake plants poisonous to dogs?
- Yes. The ASPCA lists the snake plant (Sansevieria trifasciata) as toxic to dogs. It contains saponins, which can irritate the gastrointestinal tract and cause nausea, vomiting, and diarrhea if a dog chews or swallows any part of the plant.
- What happens if my dog eats a snake plant leaf?
- Saponins in the leaf typically cause GI upset, most commonly drooling, nausea, vomiting, and diarrhea. Signs are usually mild to moderate, but a large ingestion, a small dog, or persistent vomiting/diarrhea can lead to dehydration. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 if signs appear or a large amount was eaten.
- Are snake plants also toxic to cats?
- Yes. The ASPCA lists the snake plant as toxic to cats as well as dogs (and horses), with the same saponin toxic principle and the same vomiting and diarrhea signs. Keep it out of reach of all household pets.
