Pros

Decent pay for little to no experience. The only part of this job I enjoyed was the people I worked with.

Cons

There is no actually animal care. You are doing a job to raise mice with the most basic of care. They are in little shoe boxes with cardboard rings as enrichment. They say they don’t want to waste them but I would throw away more mice than we would keep. They also didn’t pay me for a month which is illegal according to NC law. And they didn’t pay for coworker for two months.
