I've played this game since I was little. It involves you managing a zoo. You can build almost anything you want. Building exhibits for the animals usually requires you to meet their needs first. For example, if I was building an exhibit for, say, a lion, I would first need to put down the correct biome and foilage from the area in the world it was from (in this case Africa). I could put down savannah plants from other parts of the world, but guests will judge you based on the educational factor of the exhibits. I would then need to put down food, water, toys, shelter, and a few other things to keep it happy. This game tries to be as realistic as possible without being inappropriate. "Mating" is usually just a male and a female of a species laying down next to each other. And "fighting" is two animals pawing the air, and one animal usually falls to the ground, and magically turns into a carcass. There is no blood or gore whatsoever in this game, so violence is not a issue. This game may be a bit too hard for kids under 5.
