The TV work features a man living among tigers and mimicking their actions to the soundtrack of Born Free.
The campaign is part of Kellogg's "Grrrowl for a Grrrand" competition, which will see members of the public competing for a daily prize of £1,000 by doing an impression of a tiger growling.
The TV ad campaign will run for a month and features one 30-second and three 10-second spots. It will be supported by a four-week radio campaign.
Nick Bell, executive director at Leo Burnett, said, "This is our first outing for Frosties, and Kellogg has bought a campaign quite unlike anything it has run for the brand before."
