There is only an 8% of a kitten coming home by its self.
You best off looking for it and advertising it.
I have lost my 5 month old kitten for two weeks now and she still is not back.
Check with you local council, to see if he has been involved in a road accident, not the nicest thing to do but it is better off knowing.
Really sorry and the best off luck to you and your kitten
