Hey I forgot about another suicide case. But I am not sure if this one will count. I had a cat committ suicide. Yes it is true, and I am not pulling anyone's leg. Let me tell you the story and you will know. You must know first that his hearing was good. He would go out to the road in front of our home, and lay down. Normally when an automobile would come by, any cat or any animal at that would get up and move. RIGHT! But not him, the person driving the truck or car would have to get out and pick up the cat and move him. We'll we thought that was weird, so we took him into the vet. Acording to the vet he was ok. No hearing problems, or sickness. Well about a month later the next door neibor was getting in his car to leave. My cat ran over to the car when he started, and layed under the wheel. I could not get there fast enough to stop the neibor from leaving. My cat was killed. So that was that, I never thought animals would kill them selves. But I guess some times they do.
