Is Spider Plant Toxic to Cats and Dogs?
The spider plant, known scientifically as Chlorophytum comosum, is considered non-toxic to cats and dogs. This popular houseplant, also called ribbon plant or spider ivy, is a common sight in many homes. While it is a safer choice for pet owners, pet owners should understand that even non-toxic plants can cause problems if a pet eats them in large quantities.
The main concern with pets eating spider plants is not poisoning but mild digestive upset. Any plant material can be difficult for a cat or dog to digest, potentially leading to discomfort. Therefore, while the plant itself lacks toxic compounds, moderation and supervision are still key for your pet’s well being.

What the ASPCA lists for spider plant
The American Society for the Prevention of Cruelty to Animals (ASPCA) includes the spider plant on its list of plants that are non-toxic to both cats and dogs. This classification means the plant does not contain any known toxic principles that would cause systemic poisoning or serious illness in these animals if ingested. The ASPCA database entry for Chlorophytum comosum does not list any specific toxins or related clinical signs of poisoning.
What it means in a home with pets
Having a spider plant in a home with pets is generally considered safe. Unlike truly toxic plants that can cause severe reactions from a small bite, a cat or dog chewing on a spider plant leaf is unlikely to experience a medical emergency. This makes it one of the more popular choices for people who want to have both houseplants and pets.
However, a non-toxic status does not mean the plant is intended to be a food source. The fibrous material of the leaves can be irritating to an animal’s digestive system. If a pet consumes a significant amount of the plant, it may experience mild symptoms like vomiting or diarrhea. These issues are typically temporary and caused by the physical material of the plant rather than a chemical toxin.
Points to keep in mind with a non-toxic plant
Even with safe plants like the spider plant, it is wise to follow general pet safety guidelines. Discouraging your pets from chewing on houseplants is a good habit to establish. This prevents them from developing a tendency to eat plants, which could be dangerous if they encounter a toxic one.
- Placement: Consider keeping plants, including spider plants, out of your pet’s easy reach. This protects both your plant from damage and your pet from the temptation to overindulge.
- Supervision: Supervise your pets around any new item you bring into your home, including plants. Watch for signs of excessive chewing.
- Individual Sensitivities: Just like people, some pets may have more sensitive stomachs than others. What one dog can eat with no issue might cause an upset stomach in another.
- Foreign Materials: Remember that potting soil may contain fertilizers or other chemicals that could be harmful if ingested. Water that collects in the plant’s saucer could also harbor bacteria.
When to call your vet
A non-toxic listing means the plant is not expected to poison pets, not that eating it is harmless. Call your vet if your pet shows any of the signs below after chewing on a plant.
If your cat or dog has eaten a large amount of spider plant and is showing signs of distress such as vomiting, diarrhea, or loss of appetite, it is best to contact your veterinarian. You can also call the ASPCA Animal Poison Control Center at (888) 426-4435. A consultation fee may apply. Be prepared to tell them what your pet ate, how much, and when.
