WATCH: Search for a hero is on after cat battle ends up in the Thames

Not all heroes wear capes.

The search is on for a man who rescued a cat from drowning, received absolutely no thanks from the moggy in question and then left the scene as mysteriously as he arrived.

According to ITV, the cat at the centre of the drama is called Felix and he found himself in serious trouble after a fight with another cat ended with him slipping off a dock and into the Thames.
