Looks like the tiger has a pretty decent sized enclosure. It seems pretty chill, it did not attempt to escape when they opened the goat-hatch.

"I don't know. I don't know what I was thinking. I was more lonely than hungry, I guess."

I get the sense a lot of animals categorize other animals this way: Prey / Predator / Other, and "Other" is subdivided into Irrelevant / Jerk / OK Dude / Pal. Under this scheme, animals of the same species would almost always be Jerks, OK Dudes, or Pals; usually different species preclude being an OK Dude or a Pal, but there are exceptions.

But anyone, no matter what species, can be a Jerk.
