No, bougainvillea is non-toxic to cats. The colorful bracts are chemically safe — the thorns are what make this plant a hazard.

Also known as: Paper Flower, Lesser Bougainvillea, Bougainvillea glabra · Bougainvillea glabra

What to do if your cat eats it

No toxicity action needed. For a thorn puncture: remove the spine with tweezers, clean the area and watch for swelling or infection; see the vet if a thorn is buried deep or the paw becomes inflamed.

Common questions

If bougainvillea is safe, why do cat sites call it dangerous?

The danger is mechanical — hooked thorns that puncture paws and mouths — not poison. A cat that rubs against or climbs bougainvillea risks scratches, not toxicosis.

Can my cat chew fallen bracts safely?

Yes, chemically. A large mouthful of any plant fiber may cause a simple vomit, and thorns on fallen stems are the bigger issue — rake them up.
