I guess you think the animals will smell bad because it will be hot? They are so spread out there is really no issue. Now, we used to live in Chicago and we went to the zoo in the winter a couple of times there. They move the animals indoors, like they have "the elephant house", ect. Talk about SMELL BAD! The smallish enclosed habitats were terrible. The smell almost made me sick! No, animals outside with lots of fresh air and room to roam are fine! It will be hot, but we love AK!! If you are not much of an animal lover I guess you could skip it.
