Escalation note
This plant is considered extremely dangerous. Ingestion of even a small amount can be fatal. Contact your veterinarian or an emergency animal poison control center immediately if ingestion is suspected.
What to watch for
First signs are vomiting, drooling, loss of appetite, and diarrhea (sometimes bloody) within 15 minutes to a few hours of ingestion. Over the next 2 to 3 days watch for jaundice (yellow gums or whites of the eyes), unusual bruising, increased thirst, weakness, ataxia, tremors, or seizures as liver failure develops.
Time window
Acute GI signs appear within 15 minutes to several hours of ingestion. Liver failure and neurological signs typically develop 2 to 3 days post-ingestion. Survival is possible with prompt, intensive treatment.

Call immediately — this is a true emergency. Contact your vet or ASPCA Animal Poison Control at (888) 426-4435 the moment you suspect any ingestion, even before symptoms appear.
What this means for your cat
Cats that chew on Sago Palm — even just a few seeds, leaves, or root fragments — face one of the most dangerous plant poisonings in veterinary medicine. Cycasin and related toxins cause severe liver injury and bleeding disorders, and even with intensive care a substantial portion of cases are fatal.
