Volunteering at a zoo is awesome. When I was in college, I volunteered at a smallish (but very nice) local zoo. We gave tours to school groups and stuff like that. One of my favorite things to do was that we were allowed to take out certain designated "contact animals" to give zoo visitors to really get up close to an animal and touch it a little bit if they wanted. My favorites were the red-tailed hawk (now that was REALLY cool but my arm always got tired fast) and the ball pythons. I've wanted a ball python every since and now I've finally got one!

I hope you find your experience volunteering at the zoo to be as fun and rewarding as I did!
