Is Sago Palm Toxic to Cats?

Cycas revoluta

Sago palm contains cycasin, which causes severe liver damage. It is the plant vets cite most often in fatal houseplant poisonings, and cats are more sensitive than dogs in most reported cases.

The seeds (the orange-red nuts at the centre) are the most toxic part, but the leaves are dangerous too. Because it looks like a sturdy, safe plant, owners often keep it within reach.

Which parts are dangerous

• seeds
• leaves
• stem

What to watch for in the UK

• Sold as a slow-growing statement houseplant, often quite expensive.
• Frequently recommended as 'hard to kill' — which is exactly why it is in so many homes.
• Small pups at the base can be knocked off and chewed.
• Do not confuse it with the safe parlour palm.

If your cat has already chewed it

1. Emergency vet immediately, even for a small amount.
2. Take a leaf or photo; say it may be sago palm.
3. Do not wait for jaundice — liver damage is already happening.

Take a photo of the plant, and a cutting if you can do it safely — identification is half of the vet's decision. Out of hours, use your practice's emergency number. This page explains risk; it cannot diagnose your cat and it contains no home treatments.

If your cat has vomited after eating a plant, see the cat vomiting guide and, if there is blood, vomiting blood. For a general red-flag checklist, use sick cat symptoms. If the worry is food rather than a plant, the can cats eat guide covers 36 everyday foods.
