My dad stepped on my kitten, and I held him in my arms for 10 minutes while he coughed up blood and died.
Oh my, that's about one of the saddest things I've ever heard. D:
I remember some of the old family cats, we had a kitten and it was sick. The vet just told us to give it some of the provided medicine which was actually (accident?)poison. It was tough times, I was eight then... :'(
