Can animals commit suicide?

idk

If a schorpioen, scorpion is surrounded door flames, it stings itself and dies because burning is the most painful way to die.

Yes

I don't think so.. My dog got ran over last night though. :(

I have heared of abused dogs refusing to eat, same with cats. I would guess so. They just don't point guns in their mouths and pull the trigger.

I guess not...

What are those things that run and jump off a cliff in groups? .-.
