Behold, the paradoxical portrait of history's most famous thought-experiment cat, caught in the eternal state of wondering if it remembered to turn off the quantum coffee maker. Our retro-styled feline friend is simultaneously judging you and not judging you until you observe which shirt size you're ordering.

Note: No cats were harmed in the making of this shirt. We think. We haven't opened the box to check.

Technical Details:

-Brown vintage-style cat illustration (alive AND dead has never looked so stylish)
-Propaganda-poster aesthetic (because quantum mechanics needs better PR)
-Pre-shrunk (unlike the probability wave function)
-Quantum-entangled quality guarantee

Perfect For:

-Physicists who are simultaneously cat people and not cat people
-Anyone who's ever tried to explain quantum mechanics using pet metaphors
-People whose cats regularly violate the laws of physics anyway
-Those who appreciate both Heisenberg and hairballs
-Quantum veterinarians (they exist in at least one universe)
