Plant safety for cats
Is dieffenbachia (डाइफेनबेकिया) toxic to cats?
ModerateListed toxic to cats by ASPCA
Yes — dieffenbachia (dumb cane) is toxic to cats and among the most painful houseplants: crystals plus an enzyme cause intense mouth burning, drooling and vomiting, and rarely throat swelling.
Why moderate: The harshest of the oxalate houseplants (crystals plus an enzyme): severe mouth pain, rare throat swelling.

Toxic parts
Leaves and stems — the crystals are released wherever the plant is chewed.
What's in it
Insoluble calcium oxalate crystals plus a protein-digesting enzyme — together they make the mouth and throat burn and swell.
How to recognise it
- A thick, cane-like stem
- Large oblong leaves splashed cream or white
Look-alikes and name traps
Aglaonema is smaller and clumping, with no tall cane — also toxic.
Symptoms to watch for
- Drooling
- Pawing at the mouth or face
- Gagging or vomiting
- Painful mouth, not wanting to eat
- Difficulty swallowing
- Rarely: swelling of the throat that makes breathing hard (emergency)
At once — the crystals hurt as soon as the plant is chewed.
What to do
Call your vet. It hurts at once, but most cats recover with supportive care.
- Take the plant away, note how much is missing and take a photo of it.
- Call your vet if your cat drools, paws at the mouth, gags or vomits.
- Go now if breathing is noisy or laboured, the face or throat swells, or your cat can't swallow (Pet Poison Helpline's rule).
- Don't make your cat vomit at home unless a vet tells you to.
Where Indian cats meet it
A common indoor foliage plant in homes, offices and lobbies.
Cat-safe swap: Calathea or maranta (prayer plant) — listed non-toxic.
