7 month old kitten that has been going out on his own for a couple of months now has not come back. He is normally in and out a few times a day and is back by dark (I never let him out after dark). He doesn't usually go too far - just the neighbours gardens.
I last saw him around lunch time. He would have come back for food at least if there wasn't a problem (unless someone else has fed him as he is very friendly). I've tried ringing his dinner bell and shaking his treat bag but no sign.
What would you do?
