Can animals commit suicide?

I reckon animals can, they have feelings too! I'm not too sure about most animals but I know some dogs may do it. have you seen Marley and Me? It was a very sad and touching movie about a family and their dog. Some dogs when they grow old and know it's time to go, they may go off somewhere away from their owners to die. My friend had a very old dog that was very ill. She crawled under the house and stayed there the whole day. My friend had to drag her dog out from under the house after searching for the dog for hours. Some animals give up their life to save their young. So animals have feelings too.

If animals could think, they would perhaps kick the bucket. animals eat when they are hungry, and sleep when they are sleepy.
