Oh yeah, that was one of the first things I wanted to switch out, but it took me some time. Had to find just *the* right cat themed curtain. Found one at a Fred Meyer store and the other on Amazon (not yet installed).
I cut the curtain in half and cut off a hunk where it lays across the stand for the toilet. This is on the 21 - can't remember how the bathroom works in the 19.
New curtain works wonderfully. It's so much softer than what ETI supplies. And it looks wwwwaaayyy better to this owner!
I've not used the one from Amazon (yet) but it looks like it'll work just fine. Take a close look at the images and see what the kitties are doing (on the one from Amazon). Cracks me up.
