Why is it “because”…?

A white cow with horns stands behind a red and white checkered table, holding a silver tray with milk products, while a black cat with white stripes and a red-haired boy sit at the table; the cow moves its head and mouth as if speaking, the boy looks at the cow and gestures with a spoon, and the cat watches them, all set in a sunny outdoor scene with a wooden fence and green hills in the background; the scene cuts to a close-up of the milk products, which are in bottles and containers with blue and white striped packaging and Russian text, before returning to the original scene.
