Yes, privet is toxic to cats. The leaves and especially the black berries contain ligustrin and saponins that inflame the gut and can affect coordination.

Also known as: Common Privet, Ligustrum · Ligustrum vulgare

What makes it toxic

Ligustrin, a bitter alkaloid, plus saponins concentrated in leaves and berries. They irritate the digestive tract and in larger amounts act on the nervous system.

Warning signs to watch for

Drooling, vomiting, diarrhea and loss of appetite within hours. Larger berry quantities can add weakness, incoordination and a rapid heart rate.

What to do if your cat eats it

Remove plant material and offer water. Call your vet the same day for confirmed berry eating; incoordination or collapse requires emergency care.
