Yes — and it is one of the most poisonous garden plants there is. Every part of angel’s trumpet, from flower to root, contains tropane alkaloids that can kill a cat.

Also known as: Brugmansia, Tree Datura, Horn of Plenty, Devil’s Trumpet (Datura spp.) · Brugmansia spp.

What makes it toxic

Tropane alkaloids — scopolamine, hyoscyamine and atropine — throughout the plant, concentrated in flowers and seeds. They block the parasympathetic nervous system, causing racing heart, overheating and hallucination-like delirium.

Warning signs to watch for

Dilated pupils, drooling or dry mouth, rapid heartbeat, vomiting, wobbliness, disorientation, tremors, seizures and dangerously high body temperature, usually within an hour of ingestion.

What to do if your cat eats it

Emergency. Go straight to a vet or animal ER and say the cat ate angel’s trumpet. Bring a sample. Do not wait for symptoms — decontamination and supportive care early give the only real chance in severe cases.

Common questions

How much angel’s trumpet kills a cat?

There is no safe established dose — a single flower or a few seeds can produce life-threatening signs in a cat. Treat any ingestion, however small, as an emergency.

Is the fragrance dangerous to breathe?

The scent alone is not considered toxic, and brief outdoor exposure is fine. The poison moves by ingestion — chewing flowers, seeds, leaves or roots.

Is devil’s trumpet the same plant?

Devil’s trumpet (Datura) is a closely related annual with upward-facing flowers, and it is equally loaded with the same alkaloids. Both belong out of reach of pets and children.
