Is Firethorn Toxic to Cats?
Also known as: Pyracantha, Scarlet Firethorn · Pyracantha spp.
What makes it toxic
No significant systemic toxins are documented, but the berries contain mild irritant compounds in the apple family. The main real-world hazard is physical injury from the thorns.

Mild vomiting or diarrhea after eating many berries, plus possible small scratches inside the mouth from thorns. Serious poisoning is not documented.
What to do if your cat eats it
Rinse the mouth and offer water if berries were eaten. Treat any deep thorn puncture that swells or oozes as a vet visit, since wounds can infect.
