7. Kilkenny Cats (Star Trek: Enterprise)
This was actually an episode that was in the pipe-line for the fifth season of Star Trek: Enterprise under Manny Coto. As we saw in season four, he liked his references and in some cases he referred not only to The Original Series, but also to elements of the Animated Series. Kilkenny Cats was to be another return to TAS and would make canon several elements of one of those episodes. The episode in question was The Slaver Weapon, written by famous science fiction writer Larry Niven. It was based on his short story The Soft Weapon, which was re-written into the Star Trek universe. If you've watched the episode, then you remember it as the one with cats (the Kzinti) in pink spacesuits. Alas, the spacesuits were meant to be grey, but the director (Hal Sutherland) was pink/grey colourblind and no one picked up on it. We're not entirely certain of the plot of Kilkenny Cats other than it was a very seriously taken episode idea - work had already begun on Kzinti starship designs for Enterprise as
Josh Finney over at Glitchwork put some together. I would have loved to have seen them attempt a screen test for make up for a Kzinti, it would either have been fantastic or the worse make up we've ever seen. Sadly, not to be.
