Pacific Yew vs. American Yew: which is safe for cats and dogs?

Pacific Yew and American Yew are frequently compared because both belong to the Taxus genus and share similar needle-like foliage and toxic profiles. It is critical for pet owners to understand that both plants are highly poisonous to cats and dogs. Every part of these evergreens, particularly the needles and seeds, contains dangerous taxine alkaloids that can lead to rapid, life-threatening systemic distress. Because ingestion of either plant is considered a medical emergency with the potential for fatal cardiac collapse, neither Pacific Yew nor American Yew should be kept in a home with pets. If you suspect your animal has consumed any portion of either plant, contact a veterinarian immediately.
