Lilac

Also known as Common Lilac. One plant, one grade per pet — the verdicts below are transcribed from primary sources and human-reviewed.

FOR CATSS1 · CAUTION

Common lilac is low-risk for cats (S1 Caution): Pet Poison Helpline notes garden lilacs are not likely to cause severe symptoms, with large ingestions causing at most mild vomiting or diarrhea — but don't confuse it with Persian lilac (chinaberry), a different and seriously toxic tree.
