I have had a feral go missing for a year! Others for long periods and in a place that was filled with cat hating humans. Of course I felt my heart sink too. Never underestimate the powers of a cat. See the picture beside my screen ID? That baby turned up here with her mother, the cat that had been missing for a year. Where had Mom been? I never knew. Cats are filled with secrets and know far more than us, mere humans. Sending all the encouragement and hope that I can find. Never give up my friend.
