How horrible. Poor kitty, RIP
I'm always worried about hitting an animal - we're in the country too so I watch for deer, dogs, cats, raccoons, opossum, fox.....And I hate running over a dead animal - it just sickens me.
I've had cats and one lost his tail under the wheels of a car, but that was all. It is hard to keep them from wandering if they get out. My dogs also have a high prey drive,too. You wouldn't believe the long list of dead bodies I've had to remove...yuck.
