They are Bullet Bills, but with black fur and a white-tipped cat tail and ears. They shoot at you on a horizonal path.
Like normal Bullet Bills, Cat Bullet Bills are fired from Bill Blasters (making a meowing sound effect while doing so). However, unlike normal Bullet Bills, Cat Bullet Bills will lock onto, and follow the player, making them similar to the Missile Bill. However, unlike Missile Bills, Cat Bullet Bills always follow a horizontal path; they cannot travel vertically.
Cat Bullet Bills will sometimes drop a Super Bell when defeated. In the level The Bullet Bill Express, Cat Banzai Bills appear, which act as red Banzai Bills.
- While a Cat Bullet Bill appeared on the early box art for Captain Toad: Treasure Tracker, they were removed on the later box art and do not appear in the released game; instead, they were replaced with Bull's-Eye Bills.
