Cat hit by a car. How does it come hime?

He is hurt, and probably hiding. You need to really find him. Could have broken leg, pelvis, ect.. he wont survive out on his own. Pain can cause shock, and he can die just from that alone. Hope you find him, and get him medical attention. Sorry, but I'm a firm believer of keepin cats INSIDE! Then they are not susceptible to disease or being hit by cars.
