Kids Reward Sticker Design: Time-Traveling Cat with ‘Future Genius!’

Create a series of lively, high-contrast vector sticker designs featuring a whimsical, time-traveling cat with the phrase ‘Future Genius!’. Each prompt should emphasize clean, bold lines, devoid of shading or gradients, with a pure white background suitable for die-cut stickers. Incorporate fun sci-fi elements like gadgets, space helmets, portals, and futuristic props to spark kids’ imagination. Utilize placeholders such as [Cat Name], [Accessories], [Pose], [Expression], and [Date] to allow customization and versatility across designs.
