What's not to love? You've got open air, the animals, and—oh my, the animals. Let it be known that we love a good mini-pig video.

Unfortunately, even with a projected increase in the demand for animal scientists, starting salaries come in as low as $25,000 per year (source). Advanced degrees bump that number up another $20,000...which, for you non-mathematicians out there, still tops you out at a measly $45,00 per year.

In any case, if you're into the animals and their sciences, we suggest you keep on schoolin'.
