Cat Ion T-shirt

Cat Ion is a clever atomic twist on the curious cat, illustrated at the center of swirling mouse orbits and inspired by the science of a positively charged atom, or cation. Designed as a symbol of optimism and forward momentum, it’s a reminder that the energy you carry can shape the world around you. Stay positively charged, think boldly, and let your ideas spark new possibilities wherever you go.

At STORY SPARK, we take great pride in creating unique human-made illustrations on soft graphic tees that allow you to tell a story and spark connections wherever you go. Make this positively charged atomic cat t-shirt part of your story, and see what conversations you can inspire.

Our garments are lightweight and super-soft due to our use of high
quality ring-spun cotton. They’re so comfortable, you might forget
you're wearing them at all! The cut of the shirts are fashion fitted, so they run slightly slimmer than a regular t-shirt cut - not pre-shrunk.

Each of our unique graphic tees are designed and silk-screen printed in California, USA. The garments are manufactured in Nicaragua in socially responsible factories that are WRAP (Worldwide Responsible Accredited Production) certified.

Machine wash cold inside-out, hang dry or tumble dry at a low setting.
