Is Inkberry Toxic to Cats?
Also known as: Gallberry, Evergreen Winterberry, Ilex glabra · Ilex glabra
What makes it toxic
Saponins and related irritant glycosides concentrated in the black berries, also present in the evergreen leaves. They inflame the stomach and intestines and can depress the nervous system.
Warning signs to watch for
Drooling, vomiting, diarrhea and loss of appetite within a few hours, sometimes with lethargy or incoordination in larger ingestions.
What to do if your cat eats it
Remove berries and foliage, offer water and monitor closely. Call your vet if vomiting repeats or the cat becomes dull or wobbly.
Common questions
Are inkberry berries the risky part for cats?
Yes — the black berry clusters carry the highest saponin load, and evergreen leaves extend the exposure season into winter when fewer plants are green.
Is inkberry related to winterberry holly?
Yes, both are Ilex species with similar saponin toxicity. Treat all hollies as mildly to moderately toxic to pets.
