So sorry to hear Munk is still not home with you.
I had a cat, Angus, disappear one night, completely out of charachter, a few years ago. Of all of mine I would have said he was the one who stuck closest to me, and would never leave home. He was a real mummy`s boy and slept on the bed all day long, only going out for an hour or so at a time.
5 months later, 2 days before Christmas, I had a phone call from the RSPCA. He had been living in an old lady`s garden for most of the time, and she was putting food out for him as she thought he had a home locally and was just visiting her. I had moved about 6 weeks before so he hadnt been out for long, and prob lost his bearings as to where home was.
She couldnt see well and didnt realise he had a collar and tag on. One day he was very quiet, so she got a friend to look at him and they realised he was very ill, so called the RSPCA, who advised them to take the collar off and ring me. I shot round there pdq.
He was thin, flea ridden and ill with a kidney infection. He made it through the holidays, and was with me till he died of kidney probs (prob bought on by his being ill and not treated promptly) a few months ago.
Please dont give up hope, Angus just proved to me it can come true for everyone.
