Animals CAN get depressed and starve themselves, or maybe kill themselves by ripping out their hair. (they do that when they're bothered by sudden change, like an animal or human dying or moving)

Animals can become depressed and 'loose the will to live' but I'm not sure if you would consider that suicide. I know my Mum had two cats and when one was hit by a car the other stopped eating and passed away. Does this help?

Sometimes I actually wonder about the Kangaroos here…. I hate seeing them hurt or killed, however I have been in a truck where you see one standing on the side of the road then jump out right in front of the truck….

No. They lead stress-free lives compared to humans.

Even then, during the most stressful moments, suicide should never be an option
