The only animal I’ve ever killed was a cat. With my car. While running studded snow tires.
I felt terrible, but it was dark out, and I just didn’t see the feline in time to even attempt saving its life. Since then I’ve come dangerously close to much larger animals: an elk on the side of a North Idaho highway and a number of bucks encroaching on I-90 in Montana and Wyoming. But I’ve never come close to hitting a kangaroo, and I’ve never swerved to hit an animal on purpose.
Unlike some people.
