That polar bear was depressed: https://en.wikipedia.org/wiki/Gus_(polar_bear)

He was the first zoo animal to be given anti-depressants.

There's even a song about it: https://www.youtube.com/watch?v=maQTLIWUZtw

I give my cat anti-depressants when he won't eat. It's pretty common from what the vet told me.
