The 4th of July is also a holiday animals can enjoy.
In Illinois, some of the animals at the Brookfield Zoo got patriotic treats ahead of the holiday.
The bottlenose dolphins got a floating flag made of sugar-free gelatin.
California sea lions and grey seals got "Happy 4th of July" ice and sugar-free gelatin cakes.
Brown bears also got on the fun.
They savored red, white, and blue ice blocks containing carrots, sweet potatoes, bones, apples, and blueberries.
