What Is Yew?

Yew (Taxus species) contains taxine alkaloids that block cardiac calcium and sodium channels. All parts are extremely toxic except the fleshy berry aril, and ingestion can cause sudden cardiac arrest.

How Yew Poisoning Affects Cats

The toxic principle in yew is taxine alkaloids. Taxine alkaloids block calcium and sodium channels in cardiac cells, disrupting electrical conduction and potentially causing fatal cardiac arrest. All parts are toxic except the fleshy berry aril.

The severity of yew poisoning in cats depends on several factors:

  • The amount consumed or the extent of exposure
  • The route of exposure (ingestion, skin contact, inhalation)
  • The cat's body weight, age, and overall health
  • Whether the substance was in concentrated or diluted form
  • How quickly veterinary treatment is initiated

Often fatal. Can cause sudden cardiac arrest.
