We did a really cheap solution with things that we found around our house.
We took one of those rubber made tubs and cut a hole in the top, to one side, so that the cat had room to jump up onto it. Took a cheap clearanced bathroom rug and cut the same size hole and placed it on top to catch the litter from the paws.
Worked perfectly and the dog couldn't reach his neck into it

The kitty loves it because he has total privacy.
Can we post links? If so, Here's a picture of my finished catbox: ****************************************/kvxe3b
I took material and attached it with stick on velcro, made tassles out of yard and what you dont see in the picture is we put the rug on top of that... I just didnt show it because its green, we need to get a matching brown one
