This is quite possibly one of the most awesome t-shirts I’ve ever seen, inspired by the card “Donate your body to cat science” from Exploding Kittens, NSFW edition. Available in sizes Small to 3XL.

Doctor Tinycat holds up a human heart between the words “I have no idea what I’m doing” on the front of this black 100% cotton shirt.
