Yes — tree tobacco is severely toxic to cats. It contains anabasine and nicotine, alkaloids that overstimulate then paralyze the nervous system.

Also known as: Nicotiana glauca, Mustard Tree · Nicotiana glauca

What makes it toxic

Anabasine and nicotine alkaloids in all parts, especially leaves. They bind nicotinic receptors, causing tremors, then blockade that stops breathing muscles from working.

Warning signs to watch for

Drooling, vomiting, excitement and tremors soon after ingestion, followed by weakness, staggering, slow labored breathing, drooped eyelids and collapse.

What to do if your cat eats it

Emergency. Get the cat to a vet immediately with a plant sample. Respiratory support started early is critical — once paralysis sets in, minutes matter.

Common questions

Is tree tobacco more dangerous than smoking tobacco?

Yes. Its main alkaloid anabasine is more toxic than nicotine, and the whole plant is eaten raw by curious pets rather than smoked.

Are the yellow flowers a risk if a cat bats them down?

Yes — flowers, leaves and stems all carry the alkaloids. Fallen flowers and leaves on the ground are also a hazard.
