For people not familiar with Star Trek, the USS Enterprise actually had a canon furry crew member in the Animated Series that aired in the 70s. The Caitian Lt. M'Ress appeared in 6 of the 22 episodes. I'd been thinking of doing a manip of her ever since the new Trek animated series (which also has a Caitian crew member) debuted, and I found some good stock to do it with recently.
