Taxine is present in all parts of the yew, but the seeds contain most of it.  Ingesting American yew is dangerous for felines and may cause tremors, difficulty breathing, vomiting, and may even lead to sudden death from acute heart failure. Do not wait any longer and go to a veterinarian once you notice any of the said symptoms.

Known to be the hardest of the yew species, provides excellent ground cover in forested areas. It is usually about one meter tall and has small yellowish-green leaves that taper abruptly to a tiny point.
