33) Don’t Make The Animals Sick
We understand not climbing on zoo fences. It seems like an aggressive sign, though, mentioning not to climb on the fence because the animals will get sick. Not that you would die or anything, but that the animal would suffer. Hopefully, that’s enough to deter anyone from climbing on a fence, although we don’t know who would do that in the first place because the threat of being attacked or eaten by any animal is clearly very real here (via Bored Panda).
