Safety status
What this means for your cat
Cats — extremely toxic, treat as an emergency. ASPCA lists cycads (sago palm and relatives) as toxic to cats; cycasin in every part of the plant causes severe GI signs that can progress to liver failure within days. Pet Poison Helpline notes as few as one or two seeds can be fatal.
What to watch for
Within minutes to hours: drooling, vomiting (sometimes with blood), diarrhea, and loss of appetite. Over the next 1–3 days: jaundice (yellow gums or eyes), increased thirst, lethargy, easy bruising, dark or tarry stools, and weakness or seizures as liver failure sets in.
Time window
GI signs begin within 15 minutes to several hours after ingestion. Neurologic and severe liver signs typically appear within 2–3 days. Hospitalization for several days is the norm.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) immediately — even if your cat seems fine. About 50% of cycad poisonings are fatal even with treatment, and outcomes hinge on how quickly decontamination starts.
First aid at home
If you saw your cat chew or swallow any part of a cycad, do not wait for symptoms — bring the cat and a sample or photo of the plant to the emergency vet now. Do not induce vomiting unless your vet or poison control instructs you to. Call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661) on the way.
