Is Schefflera Toxic to Cats?

Did you know Schefflera is one of the most prized Feng Shui houseplants believed to bring luck and wealth?

But, not many growers know that this attractive houseplant contains resin that is toxic and may cause poisoning.

Schefflera may look innocent, but every part of this tropical plant contains tiny needle-like calcium oxalate crystals that may cause severe poisoning in cats when touched or consumed.

It is toxic to both humans and animals, where the severity of toxicity is more likely seen in cats, leading to illness and even death.

Even ASPCA fervently calls out to keep them away from your cat at all costs.

Read on to find out what dosage of calcium oxalate from Schefflera may poison your cat and how to identify signs before it’s too late.

Is Schefflera Toxic to Cats?

Schefflera is known to be toxic to cats. However, the plant falls into toxic houseplants that cause poisoning in both humans and pets.

In fact, all species of Schefflera is known to be toxic but at varying level; hence, the severity of toxicity will differ depending on the dosage of intake.

However, it is the cat that mainly falls prey to Schefflera poisoning.

The oval-shaped, all-green Schefflera leaves easily lure small animals like cats and dogs to touch and nibble on the leaves.

Because cats are more agile, they tend to easily climb onto the plant container, raising the risk of poisoning cats.

Therefore, ASPCA strictly recommends pet owners keep the plant away from their cat’s reach.

What Causes Schefflera Poisoning?

Schefflera, also known as Dwarf Umbrella Plant, Australian Ivy Pal, Octopus Tree, or Starleaf, is easily found in China and Southeast Asia.

It is so commonly grown in Thailand and China that locals use the plant to produce asthma, allergy, and common cold medicines.

However, the same cannot be said about the Schefflera grown as the houseplants, which always comes with a warning!

The resin called Calcium Oxalate Crystal found in the Schefflera is the leading cause of poisoning. The plant actively produces throughout its stem and leaves.

Calcium Oxalate CrystalsThe minerals produced from oxalate are naturally found in green plants, combined with Calcium.
ProteinaseIt breaks down protein in cells to release nucleic acid
Proteolytic EnzymeThey help break down protein, releasing toxic agents

Some Schefflera may also produce proteinase and Proteolytic enzymes that release toxic agents like histamines and kinins.

When your cat nibbles on the leaf, lick the wounded stems, or eat fresh fallings from the plant, the active toxins will enter their lungs and digestive tract, leading to poisoning.

When left untreated, toxins enter their bloodstream, causing severe problems to significant body organs.

The crystals are needle-shaped and pointy, which affect sensitive tissues in the mouth, tongue, throat, digestive tract, and later bloodstream.

Note: The insoluble oxalate found in Schefflera can accumulate in the renal glomeruli, leading to the formation of kidney stones and other renal disorders in humans.

What Parts of Schefflera are Poisonous to Cats?

Almost every part of the plant contains varying calcium oxalate, proteinase, and proteolytic levels. Hence, eating any part may lead to poisoning.

Even if they nibble on the tip, the plant will release a burst of crystals into their mouth.

But not just that, the water collected on the saucer may also contain some crystals, which can lead to poisoning when your cat drinks from it.

You should keep the plant completely out of your cat’s reach.

However, the good news is that not all toxicities lead to significant damage, and most poisoning cases can easily be treated.

Signs or Symptoms of Schefflera Poisoning

Diagnosing Schefflera Poisoning in Cats

Diagnosing plant poisoning in cats can be slightly tricky because many of its symptoms correlate to other common problems in cats.

The signs of plant poisoning may correlate to food poisoning, skin problems, parasitic infection, and digestive issues (Tapeworm).

  • Plant leaves and stems lying on the floor
  • The residue of leaves and waxy substance around the cat’s mouth
  • Visible signs of bite marks on the plant
  • Saucer’s water spilled on the floor

A thorough general diagnosis includes taking blood and urine samples, endoscopy, and physical exam.

  • Most vets recommend a physical exam to identify pale gums due to internal bleeding, a racing heart, coughing up blood, etc.
  • A blood sample will help obtain a biochemical profile, complete blood count, and electrolyte level.
  • While urinalysis helps identify damages to the liver and kidney from calcium oxalate crystals.
  • An endoscopy may follow when the prior results may seem inconclusive.

Treatment for Schefflera Poisoning in Cats

  • Wear a mask and pick out plant residue from their mouth or wash it with clean water to remove any residue.
  • Wrap them in a towel so they would not struggle.

How to Prevent Accidental Schefflera Poisoning in Cats?

Cats are innocent yet curious beings who are hard to keep in one place.

To make matters worse, they like the taste and texture of plants that may lure them.

Hence, it is not uncommon for these agile beings to get close to houseplants and sometimes nibble on them.

However, you can prevent this by keeping safety measures in place.

  1. Make Your Plant Unappealing: Cats dislike the taste and smell of anything citrus; hence, you can spray some lemon, lime, or orange juice diluted with water on the plant leaves.
  2. Apply Neem Oil: Regularly apply neem oil, a herbal pesticide, to ward off cats and pests from your Schefflera plants.
  3. Gift Them a Plant: Providing them with a plant to play with, such as wheat, barley, or cat grass, will draw their attention away from Schefflera.
  4. Apply Chemical Pray: Use sprays like spritz deterrent to irritate the cat from coming close to the plant.
  5. Spray Vinegar-Water Solution: Cats dislike the vinegar taste, which will keep them coming close to Schefflera.
  6. Use Fragrances: Natural fragrances like lavender and rosemary will help your cat away from the plant.
  7. Add Hurdles: Cover the plant surrounding with a plastic carpet protector with a knobbly side up.
