Coontie Palm

Symptoms reported in cats

Most serious first.

1. 1
   Jaundice (icterus), abdominal swelling (ascites), and liver necrosis Delayed; typically develops within 48–72 hours post-ingestion. · The toxin cycasin causes severe liver damage. Hypoglycemia (low blood sugar) may develop secondary to hepatic necrosis, requiring dextrose supplementation.
2. 2
   Persistent vomiting, diarrhea (often bloody or dark/tarry), anorexia, and abdominal pain Rapid; typically within 15 minutes to 4 hours of ingestion. · Gastrointestinal signs are usually the first to appear. The vomiting can be persistent, and the resulting hemorrhagic gastritis can lead to severe dehydration.
3. 3
   Ataxia (wobbly gait), tremors, seizures, depression, and muscular paralysis Variable; can occur early or develop alongside liver failure. · The neurotoxin BMAA contributes to CNS effects. Paralysis and coma are potential outcomes in severe cases.Coagulopathy (Bleeding Disorders)
4. 4
   Bruising (petechiae or ecchymotic hemorrhages), abnormal bleeding, and blood clots Delayed (associated with the progression of liver failure). · As the liver fails, it cannot produce necessary clotting factors, leading to internal and external bleeding issues.
5. 5
   Lethargy, weakness, and increased thirst (polydipsia) Within hours of ingestion. · Ingestion of just 1–2 seeds can be fatal due to the high concentration of toxins in them.

Important notes

Coontie Palm (Zamia integrifolia) is a small, ground-level cycad native to Florida and the Caribbean, commonly used in landscaping as a low-maintenance ornamental. Despite the "palm" name, it is not a true palm — it belongs to the ancient Cycadaceae family and carries the same severe hepatotoxic risk as all cycads. It contains cycasin, a methylazoxymethanol glycoside that the gut converts into a potent liver poison, and the neurotoxin BMAA. Seeds carry the highest concentration and are the most dangerous component.

• Symptoms: Vomiting, bloody diarrhea, severe lethargy, jaundice, abdominal pain, seizures; irreversible liver failure within 24–72 hours without treatment.
• Easily mistaken for a safe plant: Its low, fern-like appearance makes it seem innocuous, but it is equally deadly to all cycad species.
• Action: Life-threatening emergency. Bring the cat and a sample of the plant to a vet immediately — do not wait for symptoms to worsen.
