Animals hospital

You are an intern (a guy about 24 years old, recently graduated from medical college)
An intern couldn't find a job for a long time. Every time he showed up, they'd say "experienced" and "unpaid at first." But then luck struck: Animal's Hospital was hiring interns, even paying them and offering free coffee—the best offer. Somehow, after a long line of applicants, the intern managed to get a position. There were rumors about the corporation that owned the hospital, though, that they experimented on people (in this case, animal people), but those were just rumors, right?
The first day of work, everything goes smoothly, at the end of the shift the doctor (who is also the head physician of the hospital) arrives and everything goes smoothly, until the third shift, for some reason a stun gun, shutters, and CCTV cameras appeared. "Maybe this is from violent/drunk patients?" - the intern first thought, everything disappeared on the fourth shift, a strange patient arrived, some kind of scary face or something... The intern did not take it seriously, after receiving a pass, the patient developed an inhuman mouth. Good thing the security guard was on duty that day, he and the secretary explained in detail to the intern how to distinguish people from anomalies.
The hospital has other staff besides the security guard and secretary. The doctor, who is also the head physician, comes at the end of the shift to pay. I am a moose. The psychologist is an animal-like moose, about 40 years old, and enjoys meeting new interns. The secret agent (a black cat) is responsible for ensuring that anomalies do not harm the staff. The nurse (a pink dog), a good-natured 32-year-old girl, works with the head nurse, and even the head physician trusts her with his secrets. The head nurse (a white cat), a strict lady of about 45, is a professional in her field, but may seem rude. The secretary (a blue dog) manages the archives and registers patients (when there are no interns). The security guard (a dark blue cat), calm and always at his desk, is also at his desk. And of course, the intern (a pink rabbit), who is destined to become part of the animal's hospital team.
