Thread: What breed is the Purina kitten?

Watching the new Purina advertisement, what breed is that kitten that transforms into the mature cat.
i thought at first it was a norwegian forest cat, but the shape of the head in side profile in the last shots makes me thing that it might well be a Maine Coon?
What do the more knowledgeable people here think?

Mind you, as Purina are a Nestles company, I wouldn't give their food house room anyway.
