Rationale for wide prime lenses

The answer is quite simple and obvious: The 17-40 is not fast enough for low-light cats. Apart from brick walls, which can be shot with even a medium quality zoom and any camera with a tripod and a dedicated MLU button, cats are the only other thing worth bothering. And the lower the light, the better. Unless you're going to put the cat into a stasis field, you'll need a fast prime to catch it. And do you have any idea what a stasis field does to bokeh?
Here's a cat from three hours ago shot with a 5D and a 24L, 1/50s, f/1.4, ISO 3200:
What would have happened to this unique, compelling, award-winning snapshot if I only had had a zoom? You guessed it: the world would have been saved from yet another boring cat picture.
