It sounds like bad dad! I know how you must feel as my kitten Benjamin strayed away from home. He was so friendly and soppy.
I put a card in the newsagent's window with a picture, but I got no replies and as the time went by I gave up ever seeing him again.
About two years later a friend rang me to say that he thought he saw Benny in a nearby street about a mile away. I went for a look, and sure enough it was him. He even remembered me and came straight away when I called his name. He had a new home by this time, and the family he lived with loved him just as much as I did, and he had a really nice home.
I was so sad to leave him there, but I thought it was best. I saw him lots after that, and he was really happy. I got another kitten from the shelter, but I never forgot Benjamin.
