English Yew vs. Japanese Yew: which is safe for cats and dogs?

English Yew and Japanese Yew are frequently compared because both belong to the Taxus genus, leading many pet owners to wonder if their shared classification implies a shared level of risk. Unfortunately, both plants are extremely dangerous to cats and dogs. Every part of these evergreens, including the needles and seeds, contains potent taxine alkaloids that can cause severe systemic distress and even fatal cardiac events. Because both English Yew and Japanese Yew are considered highly toxic, neither is safe to keep in a home with pets. If you suspect your animal has ingested any portion of either plant, seek emergency veterinary care immediately.
