Son's new kitten

My son took the new kitten to the vet this morning.  The vet told him it was only about 5 weeks old, not even old enough for a rabies shot.  He also told my son that he didn't think he needed the rabies shot.  He is keeping the kitten,of course.  I finally got the details.  He was rushing to his ex's house to drop off his son.  The kitten was just sitting in the middle of the street.  He slammed on his brakes, got out to catch the kitten.  It ran under his truck and climbed into the wheel well.  He got scratched and bitten when he dragged it out.  He wrapped it in his shirt and took it with him.  With a kitten that small just sitting in the middle of the street, I figure my son came along immediately after someone just stopped in the street and put it out.  Anyone who does that should be stripped naked, staked out near a fire ant hill and left to suffer.  Sorry.  I have no patience with anyone who mistreats the defenseless ones-animals, children, or old people.  And that kitten will be with my son for the rest of it's life.  I raised a wonderful human being.
