The models you see in “Animal Hospital” come from the Roblox game Animal Hospital Anomaly.

What game the models are from

  • The specific 3D model called “Secret Agent” that appears in Animal Hospital-style content is explicitly credited as coming from the Roblox game Animal Hospital Anomaly.
  • That means the character models, creatures, and environment designs you recognize from “Animal Hospital” videos or fan uploads are based on assets from that Roblox title, not from a standalone console/mobile game with the same name.

Related games that might be confusing you

There are several other games with “Animal Hospital” in the title, but they are different:

  • Animal Hospital (2023) – a veterinary simulation game by Tivola/Jumpgate on PlayStation, Xbox, and Switch. This is a conventional vet sim with mini-games, not the one using the Roblox “Secret Agent” model.
  • Pet Vet 3D Animal Hospital – a Steam game where you run a pet clinic with check-ups, training, and riding.
  • Zoo Hospital – a zoo-based vet sim where you treat wild animals in minigames.
  • Various mobile “Animal Hospital” apps on Google Play that are generic pet clinic sims.

None of these are the source of the specific Roblox-style models; those come from Animal Hospital Anomaly on Roblox. Information gathered from public forums or data available on the internet and portrayed here.
