Is Weeping Eastern Hemlock toxic to cats?

Tsuga canadensis 'Pendula'

Mildly toxic to cats

Mildly. The ASPCA lists weeping eastern hemlock as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Tsuga canadensis is not listed by the ASPCA as toxic to cats or dogs. However, foliage ingestion in significant quantity may cause mild gastrointestinal upset; treat as low-risk but supervise grazing pets as a precaution.
