Is mistletoe toxic to cats?
American mistletoe is toxic to cats (S3 Toxic): its lectins and phoratoxins cause vomiting and diarrhea, and larger amounts can slow the heart, drop blood pressure, and make breathing difficult — a holiday sprig with berries needs to stay out of reach, not just out of sight.
