Is Snake Plant Toxic to Cats and Dogs?
Yes, the snake plant is toxic to cats and dogs. This popular houseplant, also known as Mother-in-Law’s Tongue, Golden Bird’s Nest, or Good Luck Plant, contains natural chemical compounds that can cause gastrointestinal upset if a pet chews on or eats it.
The American Society for the Prevention of Cruelty to Animals (ASPCA) identifies the toxic principles in Sansevieria trifasciata as saponins. These substances are the cause of the digestive symptoms seen in pets that ingest parts of the plant. While the plant is a common sight in many homes, pet owners should be aware of the risks it poses to their animals.

What the ASPCA lists for snake plant
The ASPCA plant database is a primary resource for pet poison information. It lists the snake plant as toxic to both dogs and cats. The specific toxic compounds identified in the plant are saponins. These are naturally occurring chemicals that can irritate the digestive system of animals.
According to the ASPCA, the clinical signs of snake plant ingestion in pets are related to this irritation. The listed symptoms include:
- Nausea
- Vomiting
- Diarrhea
The entire plant is considered toxic, including the leaves and roots. The severity of the symptoms can depend on how much of the plant a pet consumes. Even a small amount may cause a reaction in a sensitive animal.
What this means in a home with pets
Having a snake plant in a home with cats or dogs requires careful management to prevent accidental ingestion. Pets, especially younger or more curious ones, may be tempted to chew on the plant’s stiff, upright leaves. Boredom or a lack of other appropriate chew toys can also lead a pet to nibble on houseplants.
Any amount of the plant can potentially cause the nausea, vomiting, and diarrhea noted by the ASPCA. It is always safest to assume a pet might interact with any plant within its reach. Pet owners should supervise their animals around houseplants and be able to recognize the signs of potential poisoning.
Keeping cats, dogs, and this plant apart
The most effective way to protect your pet is to ensure they cannot access the snake plant. Prevention is the best strategy for pet safety. Place the plant in a room that is off limits to your pets, such as a guest room or office where the door is kept closed. Using high shelves, hanging planters, or plant stands that are too tall or unstable for a pet to reach or knock over can also be effective.
Provide plenty of safe alternatives for your pets to chew on, such as appropriate toys for dogs or cat grass for felines. This can help redirect their natural chewing instincts away from potentially harmful houseplants. Always supervise pets when they are in rooms with plants, and check your plants regularly for any signs of chewing or missing pieces.
When to call your vet
If your pet chewed or ate part of this plant, call your veterinarian or an animal poison control line. Note which plant and which part, how much may be gone and when, and take a photo or a piece of the plant with you.
