There are better civilization incrementals out there. The game has nothing to do with kittens, it's all text-based with garish Times New Roman and atrociously bad layout. Apart from the catnip being food it could be any generic setting. The game is extremely sluggish and stingy with resource gain, so that very long waiting periods are required to get anywhere which cannot be accelerated with active play. It's also broken in odd ways, where the production of certain key resources never appears after researching its relevant technology, which blocks further progress.
