The player can attempt to stop the cat if they are quick enough, or they will have to start the tidying process all over again. The cat will appear at random points and try to mess up the area that the player has been tidying up. While A Little to the Left is mostly a relaxing, casual game, there is a chaotic element in the form of a mischievous cat.
Many of the puzzles have more than one possible solution. The player is presented with various messes to tidy up, such as a row of bottles that fit together in a particular way or stacks of cans that need rearranging, but the player can only move the top can of a given stack. A Little to the Left is essentially a game about keeping a home tidy.
