Mildly toxic — irritant
Mildly toxic. Snake plants contain saponins that cause nausea, vomiting and diarrhoea in dogs and cats if chewed. Unpleasant but rarely serious.
Snake plants (Sansevieria / Dracaena trifasciata) contain saponins, natural compounds that foam and irritate the digestive tract. When a pet chews the tough leaves, it typically causes nausea, drooling and gastrointestinal upset. The firm leaves are not especially appetising, so large ingestions are uncommon, and serious poisoning is rare — but the vomiting and diarrhoea can leave a small pet dehydrated.
Both dogs and cats react similarly with stomach upset. Bored chewers and kittens exploring with their mouths are the usual cases.
Remove access to the plant and watch for vomiting and diarrhoea; encourage water. Most pets recover with no treatment, but call your vet if symptoms are severe or persistent, or your pet is very young or small. A poison helpline can advise if you are unsure. Place snake plants out of reach or swap for a non-toxic plant.
