Updated July 2026 · Codes verified regularly
Getting Started in Animal Hospital
Animal Hospital is a chaotic veterinary simulation game where you diagnose and treat animals while dealing with mysterious anomalies that warp reality around the clinic. Your shift starts with normal patients, but as the day progresses, things get strange.
The core gameplay loop is: triage patients at the front desk, run diagnostics in the lab, and administer treatment in the ward. Each patient has a set of symptoms you must identify using tools like the X-ray scanner and blood analyzer. Anomalous patients have impossible symptoms — a cat with no skeleton, a dog whose heartbeat is backwards. Learn the normal vitals first so you can spot when something is wrong.
Anomaly Guide & Survival Tips
Anomalies are categorized by threat level. Mimics (S-tier) appear as normal patients but attack when treated — watch for patients with mirror-inverted ID tags. Shadow Patients (S-tier) flicker in and out of visibility — use the UV light to reveal them before they reach other patients.
Void Creatures (S-tier) distort space around them: doors lead to wrong rooms, hallways loop back on themselves. When you see the Void effect (pixelated edges on walls), quarantine the area immediately. Glitch Nurses (A-tier) walk through walls and administer wrong treatments — they always have a slight static overlay. If a nurse's voice crackles, lock the medicine cabinet.
