My cat ate Cardboard Palm - what should I do?
Zamia spp.

Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, lethargy, jaundice, and potential liver failure.
Escalation note
This plant is extremely dangerous. Ingestion of even a small amount can be fatal. Contact your veterinarian immediately if you suspect ingestion.
First aid at home
Call ASPCA Poison Control (888-426-4435) or your vet immediately, even if your cat looks fine. If it's safe, remove any plant material from the mouth and bring a sample or photo of the plant for identification. Do not induce vomiting at home — wait for veterinary direction.
What to watch for
Drooling, vomiting, and diarrhea typically come first, often within an hour. Watch over the next day for lethargy, refusal to eat, increased thirst, and yellow gums or yellow whites of the eyes — those signal the liver is being hit.
Time window
Initial GI signs appear from 15 minutes up to several hours after ingestion. Liver enzyme abnormalities typically show on bloodwork at 24–48 hours, and acute liver failure may develop 2–3 days post-ingestion.
When to call the vet
Call immediately on suspected ingestion. Do not wait for symptoms — bloodwork can stay normal for the first 24 hours while liver damage is already underway, so home monitoring is not safe with this plant family.
What this means for your cat
Cats: assume the worst with any cardboard-palm-type cycad. Every species in the Zamia genus contains cycasin, which the gut converts into a potent liver toxin. Cardboard palms kept in homes are a recurring cause of severe poisoning in curious cats — and a small chew can be enough.
