Zoetis Inc. 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 directly markets the products in approximately 45 countries, and sells the products in more than 100 countries. Operations outside the United States accounted for 50% of the total revenue.

Zoetis builds on six-decade Pfizer history and aims for high tech innovative manufacturing technologies. Zoetis products include: Apoquel, Cerenia, Convenia, Dectomax, Draxxin, Excede, Excenel…
