Kitty Catalyst is an incremental game where you raise and breed cats, and use them for science.

Originally created for web and mobile, codenamed "cat-fu". Yes, this game was created and conceived prior to Mewgenics. Yes, there's a kind of similar professor looking dude in the tutorials, but he's actually modeled after the Tamagotchi Game Boy game professor. You can still play this on Kongregate.
