Big room, like 15x15 meters/50x50 feet. All of these aminils are wild, fully grown, in their best years, and have an empty stomach. There are no objects in the room. There's no window. There's a lamp and electricity cables in the ceiling that you can't reach, not even if you climb on one of these aminils. You have no tools, not even clothes, shoes, accessoires, nothing, you're naked. You're not vaccinated against anything.
