Cats: treat any chew as a medical emergency. Every part of this cycad contains cycasin, a glycoside that the gut converts into a liver toxin, and ASPCA lists the whole plant as toxic to cats. Seeds carry the worst dose, but a few leaf bites are still enough to send a cat to the ER.
First signs are usually drooling, vomiting, and diarrhea — sometimes within minutes. Over the next several hours watch for lethargy, refusal to eat, and increased thirst. Jaundice (yellow gums or yellow whites of the eyes) signals that the liver is taking damage and is a red-flag finding.
GI signs typically appear within 15 minutes to a few hours of ingestion. Liver enzyme elevations show up on bloodwork at 24–48 hours, and acute liver failure can develop 2–3 days post-ingestion.
Call immediately — don't wait for symptoms. Bloodwork can stay normal for the first day while liver injury is already underway, so symptom-watching at home is not safe with this plant.
Time matters. Call your vet or ASPCA Poison Control (888-426-4435) immediately, before signs appear. If it's safe, gently remove any plant material from your cat's mouth and bring a piece or clear photo of the plant for identification. Do not induce vomiting at home — that decision is for the veterinarian.

The Cardboard Palm contains cycasin, which can cause severe liver failure and death in pets.
Yes, cardboard cycad (Zamia furfuracea) is highly toxic to cats. It contains cycasin, an extremely potent toxin that can cause life-threatening liver failure even from a small amount. This is a medical emergency — contact your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately if your cat has touched or eaten any part of this plant.
Early signs — often within 15 minutes to a few hours — include drooling, vomiting, and diarrhea. Over the following hours watch for lethargy, loss of appetite, and increased thirst. Jaundice (yellow gums or yellowing of the whites of the eyes) is a red-flag sign that liver damage is underway and requires emergency care. Liver enzyme elevations may not appear on bloodwork until 24–48 hours after ingestion, and acute liver failure can develop 2–3 days later.
Call your vet or ASPCA Poison Control (888) 426-4435 immediately — do not wait for symptoms to appear. Gently remove any plant material from your cat's mouth if it is safe to do so, and bring a piece of the plant or a clear photo for identification. Do not try to induce vomiting at home; that decision must be made by a veterinarian.
Cardboard cycad contains cycasin, a toxin that causes severe liver damage. What makes it especially dangerous is that bloodwork can appear normal for the first 24 hours while liver injury is already progressing, meaning symptom-watching at home gives a false sense of safety. Because the window for effective treatment is narrow, vets recommend calling immediately — even if your cat seems fine — rather than waiting to see if signs develop.
