Yes, I have, and the funny thing is that even though it happened about 8 years ago, I just recently thought about it again.

I, too, was driving down the road and saw a dead cat. He also was right in the middle of the road. I was going home from my parents (at that time we lived on the same street about 3 blocks from each other). I got out of the car and he was still warm but I saw no breathing and could not feel a pulse. I had some newspaper in my car so I spread some out and put him in my car and drove back to my parents. Of course, I was boo-hooing the whole way and I scared my parents when I busted back in the house in a full-bore bawl. My mom came out and looked at him when I said I thought he was still alive but she said he was dead. My dad dug a grave and when I went to lift him out of my car I saw a little urine and feces on the newspaper. That's when I knew that he had been alive when I put him in my car and he passed while we were digging his grave. I knew that since he was minutes from death when I saw him there was nothing I could have done for him, but I really wished I would have at least gotten him out of the back of my car and stayed with him during his last minutes. He was a very large muscular pure white cat, and I couldn't help but notice he was not neutered and had no tags.

I know how you feel, Heather, the anger and the helpless feeling. I'll say a little prayer so that maybe your anguish will be eased. And bless you for being so caring.
