Does Sill Cats use AI-generated content?

Yes. The developers disclose AI-generated content on the game's Steam page:

This app uses AI tools during the development process, for example to configure some behavior algorithms. All cat sprite art consists of hand-drawn works by human artists, purchased under a commercial license. No generative AI is used during gameplay.

Self-reported by the developer under Steam rules: it covers AI content that ships in the game, not tools used to make it. Steam page checked on Oct 27, 2026. How to filter AI games on Steam
