Small problem with the enclosures?

[Orque41]

I just have a question with these photos the first one how did you manage to put the animals with his fences because I don't put animals with his fences (the photo) he says that they are not in an enclosure




And for the other photo how did you put the vivarium animals like in the photo and how to do

1st photo: with the use of nul barrier and the scenery fences. The animals appear to not be able to pass the rock, so you can place the fences outside the habitat without having the risk of animals getting out of bounds.

2nd photo: Just by placing them in a building grid and adding walls around.

(These photo's are not mine, just helping a bit)
