Is Schefflera Toxic to Cats and Dogs?

By the Animal Wellness Desk · Facts last checked October 21, 2026 · General information, not a vet visit

The Schefflera plant is toxic to both cats and dogs. Ingestion of any part of this popular houseplant can cause significant discomfort for a pet.

The toxicity comes from calcium oxalate crystals found within the plant’s tissues. When a pet chews on the leaves or stems, these sharp, microscopic crystals are released. They embed themselves in the soft tissues of the mouth, tongue, and throat, causing immediate pain and irritation. This is a mechanical type of irritation rather than a systemic poisoning.

Schefflera: what the ASPCA database lists

What the ASPCA says about Schefflera

The American Society for the Prevention of Cruelty to Animals (ASPCA) lists Schefflera as toxic to cats and dogs. This plant is known by several common names, including Umbrella Tree, Australian Ivy Palm, Octopus Tree, and Starleaf. Its family is Araliaceae.

The toxic principle identified is calcium oxalate crystals. The ASPCA notes that contact with these crystals can lead to a range of clinical signs in pets, including:

• Oral irritation
• Intense burning and irritation of the mouth, lips, and tongue
• Excessive drooling
• Vomiting
• Difficulty swallowing

What this means in a home with pets

The presence of a Schefflera plant requires careful management in a household with cats or dogs. Since the irritation is caused by physical crystals, a pet does not need to swallow the plant material to be affected. A few exploratory bites or even just chewing on a leaf can be enough to release the sharp crystals and cause a painful reaction in the mouth and throat.

The initial symptoms can be very distressing for the animal. All parts of the Schefflera plant, including fallen leaves, should be considered a potential hazard to pets.

Keeping pets and this plant separate

The most effective way to prevent a negative reaction is to ensure pets cannot access the Schefflera plant. Place it in a room that is consistently off limits to your pets. Alternatively, positioning the plant on a very high, stable surface or in a location that your dog or cat cannot reach is another option. Be particularly mindful of cats, who can climb and jump to access high places.

Always supervise pets when introducing a new plant into your home. Regularly check the area around the plant for any fallen leaves or stems and discard them immediately. Pet-proofing your home by keeping potentially toxic items out of reach is a fundamental part of responsible pet ownership.

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.

If you suspect your cat or dog has chewed on or ingested any part of a Schefflera plant, contact your veterinarian or a pet poison hotline right away. Be prepared to share what part of the plant was eaten, how much, and when it happened. Do not attempt to induce vomiting or provide any home remedies without professional veterinary guidance.
