Yes. The ASPCA's Snake Plant entry lists the snake plant (Sansevieria trifasciata) as toxic to dogs and cats, with saponins as the toxic principle. If your pet chewed or swallowed any, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
For growing it, see the snake plant care guide.
What happens if a cat or dog eats a snake plant
The ASPCA's Snake Plant entry lists these clinical signs for dogs and cats: "Nausea, vomiting, diarrhea."
NC State Extension's Plant Toolbox page for Dracaena trifasciata lists the flowers, fruits, leaves, roots, sap and stems under "Poison Part," gives the toxic principle as saponins and rates the poison severity as "Low." Its symptom list is longer than the ASPCA's: "vomiting (occasionally with blood), depression, nausea, diarrhea, anorexia, hypersalivation, dilated pupils (cats)." The same page notes, "The sap can cause skin irritation."
What to do if your pet ate some
Call your veterinarian, or call the ASPCA Animal Poison Control Center, which says it is available "24 hours a day, 365 days a year." The ASPCA's Snake Plant entry tells owners to "call the ASPCA Poison Control at (888) 426-4435 or contact your local veterinarian as soon as possible," and notes, "A consultation fee may apply."
Have the plant's name ready. The ASPCA lists it as Sansevieria trifasciata; the accepted botanical name in Kew's Plants of the World Online is Dracaena trifasciata. Giving both avoids confusion. Then follow the instructions the veterinarian or poison control specialist gives you.
Are all snake plants toxic? Names, cultivars and cylindrical snake plant
Plants sold as "snake plant" go by several names, so it helps to know which one you have.
- Sansevieria or Dracaena. Kew's Plants of the World Online gives the accepted name as Dracaena trifasciata, first published in Mabberley's Plant-Book in 2017, and lists Sansevieria trifasciata as a synonym. The ASPCA entry still uses the older name, so they are the same species. The care guide explains the rename.
- Mother-in-law's tongue. The ASPCA's Snake Plant entry lists Golden Bird's Nest, Mother-in-Law's Tongue and Good Luck Plant as additional common names for the same plant.
- Laurentii, Hahnii, Moonshine and other cultivars. NC State's Dracaena trifasciata page lists 'Laurentii', 'Hahnii', 'Moonshine', 'Black Gold' and 'Twisted Sister' among the cultivars of the species, the same species the ASPCA lists as toxic to cats and dogs.
- Cylindrical snake plant is Dracaena angolensis, formerly Sansevieria cylindrica, a different species. NC State's Dracaena angolensis page states, "Toxic if ingested by cats and dogs: dilated pupils, vomiting, stomach upset, abdominal pain, drooling, weakness, depression." It gives saponin as the toxic principle and rates the severity "Low."
For any other plant sold as a snake plant, look up its botanical name before assuming either way.
Keeping a snake plant in a home with pets
- Place it out of reach. A high shelf or a stand your pet cannot climb works better than a floor spot. A cat that climbs can reach places a dog cannot.
- Pick up fallen leaves and trimmings. NC State lists the leaves, roots and sap among the plant's poison parts.
- Divide and repot away from pets. Root pieces and cut leaves count as plant material too. See how to propagate a snake plant.
- Don't rely on deterrents. No placement or deterrent spray guarantees that a pet will leave a plant alone. If your pet is a determined chewer, a plant the ASPCA lists as non-toxic is the simpler choice.
Houseplants the ASPCA lists as non-toxic
The ASPCA's plant list adds a caveat that applies to every plant: "the consumption of any plant material may cause vomiting and gastrointestinal upset for dogs and cats." With that in mind, these houseplants have ASPCA entries listing them as non-toxic to dogs and cats:
- Spider plant (Chlorophytum comosum): ASPCA entry. Care: spider plant care.
- Parlor palm (Chamaedorea elegans): ASPCA entry. Care: parlor palm care.
- Boston fern: ASPCA entry. Care: Boston fern care.
- Calathea: the ASPCA entry is genus-level ("Calathea spp."). Care: Calathea orbifolia care.
For longer lists, see plants safe for cats, plants safe for dogs and the toxic plant directory.
