What hidden areas and secrets are in Animal Hospital?

Animal Hospital hides its secrets behind NPC storylines rather than keycards:

Confirmed Secrets

• The hidden safe - after completing Ratthew's storyline (~5 visits), he leaves Ratthew's Key, which opens the safe behind the cat painting in the first unlocked corridor. Inside is lore about his missing twin sister Rattina and the Animal Corporation
• Liz's UV camera quest - during Shifts 11-12, Liz lends you a UV camera for an evidence-gathering side story. Waste it and she never comes back
• Barney's reward - hiding him from Officer Duckman earns a second coffee machine
