 Normally you'd have to wait until 10 in the morning to get a glimpse at the animals, but today you can get there as early as 7.30. This is meant to keep animals and human visitors cooler from the relentless heat we've been feeling the last few days. Here are some photos of how they're keeping the animals cool. These popsicles are specifically suited to each animal's diet and a nice cold treat for them to enjoy. Today all animal demonstrations will take place before noon to avoid peak temperatures.
