Each DOCTORATE showcases a Cat Physicist, their research specialty, and a unique ability. At the start of the game each scientist is dealt a secret DOCTORATE, and they keep this ability hidden (face down) from the other scientists until they are ready to use the ability on the card.

While you are the ACTIVE SCIENTIST, you may reveal your Doctorate at any time on your turn, by flipping it face up to show the Cat Physicist side. When you reveal your Cat Physicist you may perform the action listed on the card. Each Doctorate can only be used ONCE per GAME! So, be very careful when you use it! Some abilities are better at different points in the game.
