Sago Palm: Toxic to Pets and One of the Deadliest Plants
The sago palm is toxic to pets, and not in a mild way. If you searched whether the sago palm is toxic to pets, the answer is yes, dangerously so, and it is one plant every cat and dog owner should keep out of the house entirely.
Real talk: this one is not a “keep it up high” plant. It is serious enough that I would rehome it if you have pets.
Is the sago palm toxic to pets?
Yes. The sago palm is toxic to pets, including both cats and dogs. The ASPCA lists the sago palm as toxic to dogs, cats, and horses. Its plant name is Cycas revoluta, and I checked it before writing this guide.
This is one of the most serious entries on any toxic plant list. The sago palm toxic to pets warning is not an exaggeration, and there is no safe way to keep one within reach of a cat or dog.
Why the sago palm is so dangerous
The sago palm contains a toxin called cycasin. Every part of the plant is poisonous, but the seeds (nuts) are the most toxic of all.
According to the ASPCA, eating the plant can cause vomiting, bloody diarrhea, bruising, liver damage, liver failure, and death. Just one or two seeds can be fatal to a dog, which is what makes the sago palm toxic to pets so frightening.
Signs your pet ate a sago palm
Symptoms can start within hours. Watch for:
- Vomiting and diarrhea, sometimes with blood
- Drooling and loss of appetite
- Lethargy or weakness
- Yellowing gums or eyes (a sign of liver trouble)
- Bruising, bleeding, or collapse
Because the sago palm is toxic to pets at the liver level, signs can worsen fast even if your pet seemed okay at first.
What to do in an emergency
This is a true emergency. Do not wait:
- Remove your pet from the plant and clear any chewed pieces or seeds.
- Do not try to make your pet vomit unless a vet tells you to.
- Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately.
- Bring a piece of the plant or a photo so the vet can confirm and act fast.
Other names for the sago palm
The sago palm hides under several names. They are all the same toxic plant:
- Coontie palm
- Cardboard palm
- Cycads and zamias
If a label says any of these, remember the sago palm toxic to pets rule applies to all of them, and leave it on the shelf.
