Plant safety for cats

Is castor plant (अरंडी) toxic to cats?

DeadlyListed toxic to cats by ASPCA

Yes — castor (arandi) is deadly to cats, mainly through its seeds: chewed beans release ricin, which can cause severe vomiting, kidney failure and seizures. Signs may take a day or two, so go to a vet at once.

Why deadly: Chewed seeds release ricin, and signs can take 12–48 hours to start.

  • Toxic parts

    The seeds (beans) are by far the worst, especially chewed; pruned leaves and branches are a common way pets get poisoned.

  • What's in it

    Ricin — a protein toxin that damages the gut lining and organs.

How to recognise it

  • Tall, fast-growing shrub
  • Large star-shaped leaves, often red or bronze
  • Spiny round seed capsules
  • Shiny, mottled seeds

Symptoms to watch for

  • Burning mouth and throat, drooling, thirst
  • Vomiting and diarrhoea, sometimes bloody
  • Kidney failure
  • Seizures, coma

Signs typically start 12–48 hours after eating (ASPCA) — your cat may look completely fine at first.

What to do — now

Go to a vet now — don't wait for signs. Signs are delayed, so act before they start.

  • Take your cat, a piece of the plant (or a clear photo) and tell the vet what was eaten, when and how much.
  • Don't make your cat vomit at home unless a vet tells you to.
  • No milk, oil, salt water or home remedies.
  • Take a seed or a photo of the plant with you.

Where Indian cats meet it

A weed of vacant plots, roadsides and field edges across India, which grows over three-quarters of the world's castor. The seeds are sold in bazaars.
