I'm not seeing how you're saying that someone who had in fact slowed their speeds down driving through the neighborhood was uncaring because they hit a(nother) loose animal running in the street? Maybe there's more to the story? Usually people who slow down after an accident are choosing to try to avoid a repeat of that kind of situation, not showing how much they don't care.
Most of the time when someone hits an animal, there is not a thing in the world they could do to prevent it. There's just no time. I hit a cat many years ago... well, no, that's not true. I had a cat run between the front and back wheels of my moving vehicle... on a residential side street going uphill (25 miles/hour or less) and there wasn't a thing I could do to prevent it. As far as whether or not I care about cats, all I can say is that if I have to choose between hitting a cat and hitting you, you should run. Fast. But I didn't have any choice or time at all. It happened too fast. Ditto the jack rabbit that messed up my grill. And the 'yote that my friend hit on a road trip. Not to mention the steer that jacknifed a semi in North Dakota when my parents were there, and the numerous people injured and killed when their vehicles strike deer each year.
Animals come from nowhere, they move too fast and humans typically react too slowly to instantly avoid an accident. If you have a kitty you value.... or any other animal... the only real solution is to keep them out of the street.
I'm sorry about Vivian but I think your anger is misplaced.
