Litter box questions

[Emeraldgreen]

I just posted in that thread and then saw this one. I was talking with my husband yesterday and saying how I wish they would make litterboxes with super high sides because our foster cat Barney has a habit of getting in the box but peeing over the side. I don't think he means to but he likes to hug the sides. lol
So I asked my husband if he would cut a hole in a rubbermaid container about two sizes bigger than Barney on one of the sides. I got home and it was all set up and it's working great. Here is a picture of the box. My husband just grabbed a beat up rubbermaid that he was using for kindling so it's dirty. I didn't want to complain though because he did such a good job setting it up. I will clean it up when I change the litter.
