I've always had a cat so not long after Brandon and I got married we got our cat, Lucy. When we moved into our house, I didn't know where we were going to put her litter box. Unfortunately, we don't have a laundry room - just a closet - and I didn't want it out in the bathroom to have to look at all the time (and then there was the issue of it being out for guests to see, too). So, I got the idea to put it in the bathroom cabinets.
We took off the 2 middle doors under the sink. Since I still didn't want to look at it all the time, I decided to put up "curtains". So we hung the rod where it wouldn't hit any of the drawers or the other two doors and I measured what size they needed to be. We had some leftover fabric from the curtains in our kitchen (and what will eventually go in the den/office) and it was the right colors for the bathroom too.
Just some simple panels:
