Bad Rats: The Rats' Revenge is a 2009 puzzle video game developed by Invent4 Entertainment. Over a string of levels, the player places a set of rats and static objects to guide a ball towards a trap that kills a cat. Bad Rats was released as Invent4 Entertainment's debut game on 20 July 2009 via Steam, followed by releases on other services in 2010. While it received no reviews at release, retrospective pieces criticised the game's graphics, puzzles, and physics. Bad Rats is considered an oddity for being released on Steam while the platform's catalogue was still hand-curated. It became a popular gag gift on Steam, leading to more than 400,000 owners by 2018. A sequel, Bad Rats Show, was released on the seventh anniversary of Bad Rats in 2016.
