The cardboard cycad (Zamia furfuracea), also known as the cardboard palmcardboard plant, or Mexican cycad, is an extremely 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 cycad, but ingesting any part of this plant can cause severe poisoning. All parts of the cardboard cycad contain toxic compounds callecycasin and an unidentified neurotoxin that can be deadly to cats, even in small amounts.

  2. Take a complete history of potential exposure to the 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 cycad 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.

History of the Cardboard Cycad

The cardboard cycad 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 cycads 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.
