The cardboard palm (Zamia furfuracea), also known as the cardboard plantcardboard cycad, or Jamaican sago, is a highly toxic plant to cats. This plant is not actually a palm tree, but rather a cycad that is native to southeastern Mexico. It is commonly kept as a houseplant or used in landscaping in subtropical regions.

Cats are not allergic to cardboard palm, but ingesting any part of this plant can cause severe poisoning. All parts of the cardboard palm contain toxic compounds called cycasin and an unidentified neurotoxin that can be deadly to cats, even in small amounts.

What is the Toxicity Level of the Cardboard Palm Plant?

(Level 5) - Extremely Toxic

Should you suspect poisoning, visit your vet at once or contact the APCC 24-Hour Emergency Poison Hotline.

  • Level 1 - Minimally Toxic

    Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.

  • Level 2 - Mildly Toxic

    Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.

  • Level 3 - Moderately Toxic

    Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.

  • Level 4 - Highly Toxic

    Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.

  • Level 5 - Extremely Toxic

    All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.

** Please note: Please note that toxicity level can vary based on the amount ingested and the specific cat. It's always best to keep these plants completely inaccessible to cats and seek immediate veterinary care or call the poison hotline if you suspect your cat has ingested any part of a toxic plant.

  3. Conduct blood tests and a urinalysis to evaluate organ function
  4. Take abdominal x-rays or perform an ultrasound to check for intestinal blockages
  5. Diagnose cardboard palm toxicity based on clinical signsexposure history, and lab results

Treatment involves decontamination (inducing vomiting or pumping the stomach), activated charcoal to bind remaining toxins, IV fluidsliver protectants, and other supportive care. Prognosis depends on the amount ingested and how quickly treatment is started.

The Historical Journey of the Cardboard Palm Plant

The cardboard palm is a primitive species of gymnosperm that has existed for nearly 300 million years, dating back to the time of the dinosaurs. It is native only to a small area of eastern Mexico.

This plant gets its common name from the thick, leathery texture of its leaves. It has a short, bulky trunk that is often subterranean, with long pinnate leaves emerging in a circular formation from the top.

Cardboard palms are dioecious, meaning they have separate male and female plants. The female plants produce cones that contain bright red seeds. The entire pollination process depends on a symbiotic relationship with a species of cycad weevil.

Although popular as an ornamental plant, overcollection has caused wild populations to become endangered. It is also very slow-growing and difficult to propagate, so most plants sold are illegally harvested from the wild.
