I am so sorry, odeon.
I saw my cat being run over when I was about 14. The horrible person drove onto our front lawn to hit her. Her injuries were such that she was killed instantly. While I was crying over her, a kind man stopped and offered to bury her for me. I didn't want my mum to see my cat like this so I took him up on his offer.
Now I worry about Liam as he has been on the road a few times. It would definitely break my heart if anything happened to him. Right now he is curled up next to me on the bed.
