My cat of 13 years has disappeared. He was not the kind to go past our neighbors yard. He did act strange a for a few days before he left. He didn't sleep with me as usual or sit with me at all. My concern is that he went off to die somewhere. I have put out flyers- in mail boxes and taped them up at the street poles. I have looked everywhere. We do not usually have stray dogs in the area... it is a fairly new area. Plus I really think I would have heard something if he had been in trouble. What opinions do you have about cats going off to die?
