We just built a pretty big one at my folks for the grandkids. We built a parimeter around it with Railroad ties and dumped 10 ton of clean sand in it.
I'm ordering one of those "big dig" things that look like a seat with a backhoe to set in it later.
A little round-up along the edge and you won't have to weedeat for a year.
In this particular case study, cat shit isn't a problem, as the pair of 110lb dogs and a australian shepard that routinely cruise the area, solve said problem before its an issue.
