Oh dear how sad....at least you cared, too many wouldn't. Once when I was a teen my mother, her bf at the time and myself were driving home when I saw a cat doing bizarre things on the side of the road. I said something to my mom who told peter to pull over. I tried to get out of the car to go see the cat but my mom wouldn't let me! she ran over and picked the kitty up and he/she died right in her arms. I got out of the car and saw the poor cat had been hit by a car . We were soooo sad, we tried to find the owners too.
Let this be a lesson to everyone, KEEP YOUR CAT INDOORS! It's not worth the risk!!!!
