You're a Biologist, and you are dedicated to your field. You walk into your lab and see four grey animal containment crates with small holes at the bottom to let air pass through. You can hear muffled scratching coming from each of them as you pick up the letter on the table and read it aloud.

"Warning: Dangerous mutants inside. Proceed with caution." You utter before looking back at the cages, still hearing the frantic scratching.
