Here, at Nestlé Purina PetCare headquarters, Friskies product manager Shaun Belongie helps create eight flavors of cat food each year.

In 2011, he decided to add to his creative portfolio by devising a Friskies app for the Apple iPad featuring simple video games that humans could play with their cats. True, most cats walk by the iPad and pay no bother. But some of the more curious ones find the floating fish on the iPad screen interesting enough to paw. Nestlé Purina's experiment has garnered 500,000 downloads so far. Today, the company unveils an app for Android tablets, and says it plans to release a seventh game for cats later this year.
