If you enjoy working with animals, look into internship programs at zoos.

Having worked in the pet industry, it's both a rewarding and frustrating line of work. Pay isn't good unless you are in upper management or the owner. I've worked in various aspects from retail, import/export/distribution and service/maintenance/wrangling while paying my way through university.
Corporate and government work didn't suit me very well and I started an aquarium design/consultation and service company 4 years ago. It's work but it doesn't feel like work if you know what I mean...LOL.
Best of luck to you
