The experiment’s over. The box is open. The cat?

Murderer.


This is Schrödinger’s cat if it got tired of waiting to be observed and took matters (and a knife) into its own paws. It’s not theoretical anymore — it’s personal.


Perfect for science nerds with a mean streak, goths who passed AP Physics, or anyone who thinks thought experiments should involve a little more blood.


Features a shadowy feline holding a knife like it knows something you don’t. Spoiler: it does.


Product Details:

• 100% cotton — because dead cats deserve breathable fabric

• Available in sinister BLACK, regret-blue BLUE, espresso-shot COFFEE, and radioactive YELLOW

• Short sleeve or long sleeve depending on the season of your villain arc

• Sizes S to 3XL — we don’t discriminate by mass

• Design printed loud and sharp like a scream from inside the box

• Soft enough to wear while contemplating the collapse of the wavefunction

You’re not buying a joke, you’re buying a well-made product with a joke on it. Quality that won’t make you question your life choices.

We accept returns and exchanges within 30 days of delivery.
