So I was walking up to a friend's house and on the way I walk beside a dual carraigeway. As I walked along side a verge I saw a dead cat lying on the grass.
I kept on walking but as I did my guilt just started getting bigger and bigger that I hadn't done anything; you wouldn't just walked past a dead child that had been run over would you? I started remembering how I felt when my cat had gone missing and started to empathize with the owners who would probably be looking for her or not knowing where she was.
I got to my friends, dropped off the USB stick I had of his and started to walk back determined to do something on the way back. As I approached the spot where she'd been lying I could see she had gone. 'Great' I thought, someone has done something about it; but when I got the spot where she'd been I saw she was now lying over near the bushes (I suspect someone put her there to move her out of sight as she was definitely dead when I saw her the first time

).
I walked over and checked the collar for name tag but nothing. Then I saw the entrance to housing estate opposite and not using the underpass I ran across the carriageway (making the same mistake that was fatal for the cat).
I tried the first house and they said the house opposite had cats so I knocked the guy came out and my description sadly matched one of his cats. I walked over with him (this time using the underpass) and when he saw he it was sadly a positive ID. I stayed with him as he picked her up and started walking him back to his house.
He was visibly upset, which embarrassed him but I was quick to let him know as a fellow cat owner he had nothing to be ashamed of. As we got back over the by-pass his girlfriend had come out to meet him so I tapped him on the back and said goodbye. He thanked me for letting him know and I walked off fighting back the tears myself.
I'll pop a condolence card through his door in the week I think. So that's my good deed for the year, but one I hope I never have to make again. That said I'm so glad I did do something and not just walk past (or worse kick her into the bushes), thousands wouldn't have.
