Stone marten vs cat (Stone marten family/Steinmarder/Husmår) (best at 1080p)

Whitey had a run-in with Eatsalot (our cat) last night.
She was eating a while, then decided to run to the right (to check for mouse I assume), and met the cat. She ran off, Eatsalot in hot pursuit for a short distance. Eatsalot quickly withdrew again, and Whitey, not about to be chased off her food, returned in a threatening posture (sideways with back up, much like you'd see a cat do), and as the coast was clear, she continued eating calmly.
Eastalot returned later to check out the area, by then Whitey had already been back to finish off the food.
For comparison, a stone marten is 1.5-2 kg (3-4 lbs), whereas Eatsalot (a very old, very large, neutered male) is 6.4 kg (14 lbs).
