Owner Evy Hind, 48, caught the moment Leon turned guard cat outside her house, using lightning speed to run down the fox.
It is clear the fox was in no mood to mess with this killer cat as he quickly sprinted off.
Evy was enjoying her morning coffee on the porch when the drama unfolded.
She said four-year-old Leon has always been known for being a bit of a grumpy cat, not afraid to throw his weight around to get his way.
The housewife said: ‘Leon chased and followed the fox that came into our yard, he doesn’t like foxes and they went at it like cats and dogs.
‘With his big hair Leon obviously looks pretty scary because the fox which was bigger than him was obviously scared of a fight.
‘The fox came into his territory so Leon went into battle mode, I ended up having a super morning with a cup of coffee and my camera.’
Leon is a Norwegian Forest Cat, a breed known for its lion-like features and long hair. Is the breed’s name alludes, it is especially adapted to live in the cold Norse climate with its long hair and sturdy body.
It is thought its ancestors served as mouse catchers on Viking ships and that the modern Norwegian Forest Cat’s ancestors are the ‘mountain-dwelling fairy cat’ referred to in Norse legends.
