Is Prickly Cycad toxic to cats?
Encephalartos altensteinii
Yes — prickly cycad is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. All parts of Encephalartos altensteinii contain cycasin (methylazoxymethanol glucoside), a potent hepatotoxin. Ingestion by cats or dogs causes vomiting, diarrhoea, liver failure, and potentially death. Encephalartos is in the family Zamiaceae and shares the same toxic profile as Cycas (sago palm), which the ASPCA lists as toxic. Seek emergency veterinary care immediately if ingestion is suspected.
What to do if your cat ate prickly cycad

- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
