Yeesh, bad cat stories, although it's so great that you're little guy is doing okay, Koffee.
I cannot imagine doing that to a kitten. I found my cat when I was 8 in the middle January (-40 Celsius here). Someone had abandoned her and another cat there and her paws were so frost bitten the skin had peeled off. I'm so thankfully someone at least left them somewhere where they would be found quickly. The people who owned the home where they were abandoned took one cat and we too mine.
Ugh, Anarch, that's horrible. When I was 11 or 12 I was in the car with my mom when she accidentally hit a cat. I completely lost it and couldn't stop crying and my poor mom felt so bad. Everyone assumed I was the cat's owner because I was so upset about the whole thing.
We were lucky at my parents house because they live in a long U-shaped street in the bottom part of the U - so there's virtually no traffic except the houses on that part of the street. We were able to let both of our cats have free reign outside with no worries in 17 years.
We're not going to be letting Ketto outside anytime soon. Luckily an apartment makes that really easy. I'd be so paranoid in high traffic area's.
