I seperated my pigs because he was being a bully to the others. I just put grids in between their cages so they could still smell each other. But he was pacing back and forth trying to find a way out. At first he tried to put his front paws on the cage and jump but it didnt go to well, then he tried again and he did it. My whole family was watching and all of their jaws dropped. No one could believe what he just did. I have standard 9x9 grids. I am still in shock. I was wondering if this has happened to anyone else? if so please tell me.
