What is "zoetis"

Zoetis, Inc. (/zō-EH-tis/) is the world's largest producer of medicine and vaccinations for pets and livestock. The company was a subsidiary of Pfizer, the world's largest drug maker, but with Pfizer's spinoff of its 83% interest in the firm it is now a completely independent company. The company operates in 70 countries worldwide with recent expansions into Southeast Asia and China. Contemporaneous with the spinoff in June 2013 S&P Dow Jones Indices announced that Zoetis would replace First Horizon National Corporation in the S&P 500 stock market index.
