Hero rescues cat from river in dramatic CCTV footage

There's a reason people say cats have nine lives.

On Monday afternoon, London's Royal Docks tweeted some tense CCTV footage of Felix, the Royal Docks Management Authority's office cat.

Felix had been in a scrap with a rival cat on the banks of the river Thames and lost his footing. Luckily his tumble into the river was spotted by a nearby worker called Scott, who dashed to Felix's rescue and managed to pull him free in time.

The clip below has pretty much everything you'd need in a video: cats, drama, and -- most importantly -- a happy ending:

Good work, Scott.
