Is Snake Plant Toxic to Cats and Dogs?
Short answer: yes. Snake plant (Dracaena trifasciata, still widely sold as Sansevieria or mother-in-law's tongue) is toxic to cats and dogs per the ASPCA — but by a different mechanism than the aroids. Here it's saponins, so the trouble is mostly a upset stomach rather than mouth pain. Here's the real picture.
Quick verdict
Toxic? Yes — to cats and dogs (ASPCA-listed).
How bad? Usually mild. Stomach upset that resolves on its own is the typical outcome.
Toxic part & why: the leaves contain saponins — natural detergent-like compounds that irritate the gut and cause nausea.
What is a snake plant, exactly?
Snake plant is Dracaena trifasciata — the upright, stiff, sword-shaped leaves with green banding and often a yellow edge. You'll still see it sold under its old name Sansevieria, or as mother-in-law's tongue. It's marketed as nearly indestructible and a great "air-purifying" plant, which is why it's so common — and why pets meet it so often.
Symptoms of snake plant poisoning in pets
Signs are gastrointestinal and usually show up within a few hours of chewing:
- Nausea and drooling
- Vomiting — the most common sign
- Diarrhea
- Loss of appetite and low energy
Snake plant is on the milder end of toxic houseplants. Serious reactions are rare; the usual course is a queasy pet that recovers within a day. The exception is a very small pet that eats a lot and gets dehydrated from repeated vomiting or diarrhea.
What to do if your pet ate snake plant
- Remove any plant material from their mouth and move the plant out of reach.
- Note how much they ate and when. A nibble is very different from a chewed-up leaf.
- Call your vet, or the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply). Have the name ready: "Dracaena trifasciata, snake plant."
- Do not induce vomiting unless a vet tells you to.
- Watch for worsening: repeated vomiting or diarrhea, dehydration, or lethargy means go in.
Sure it's a snake plant?
Snake plant gets confused with the (also-toxic) ZZ plant and with safe lookalikes. Snap a photo and Nature Lenz names the exact species and flags whether it's pet-toxic. Free, no paywall.

The bottom line
Snake plant is genuinely toxic but one of the more forgiving ones — expect a queasy stomach, not a crisis. Still, the stiff leaves are tempting cat toys. Move it somewhere your pet can't reach, and if you want a similar sculptural, low-light plant that's non-toxic, a ponytail palm or a cast iron plant does the job.
FAQs
Can snake plant kill a cat?
Extremely unlikely. Snake plant is a mild toxin — the usual outcome is vomiting, drooling or diarrhea that clears within a day. The only real risk is dehydration in a very small or young pet that eats a large amount, which is why a vet call is still worth it.
Why is snake plant toxic — what's the poison?
The leaves contain saponins, natural compounds that foam like soap and irritate the digestive tract. Unlike pothos or monstera (which cause sharp mouth pain from calcium oxalate crystals), snake plant mostly causes nausea and GI upset.
Is snake plant toxic to dogs too?
Yes. The ASPCA lists it as toxic to both cats and dogs, with the same signs: nausea, vomiting, and diarrhea. It's considered mild for both.
My cat chewed a snake plant leaf — what should I do?
Remove the plant material, note how much they ate, and watch for vomiting or diarrhea. Most pets are fine with a little supportive care. If symptoms repeat or your pet seems weak, call your vet or ASPCA Poison Control at (888) 426-4435.
What non-toxic plant looks like a snake plant?
For the same upright, architectural, low-light look, try a cast iron plant (Aspidistra) or ponytail palm — both non-toxic to cats and dogs per the ASPCA.
