From Owl Rescue Centre

Verreaux's Eagle Owl demonstrating how powerful he really is. Genet never stood a chance.

From Google

Genets are small, cat-like carnivores with a long, slender body and a tail that is usually as long as the body. They are typically 40-60 cm (16-24 inches) long, excluding the tail, which can be an additional 40-55 cm (16-22 inches). Adults weigh between 1 and 3 kg (2 and 7 pounds).

I don't know just how big the one the owl caught is, but this is pretty sizable prey! The owl's size and weight are about the same as the specs on the genet.

Obviously not the same people, but this should give you an idea of the scale.
