I have 8 cats all spayed or neutered that live in my barn. I've had this one cat, Shirley (he's a boy but I found out after I named him) for 8 years. There is only one older semi wild female cat and all the others are under 2 years old. Shirley has lived with us since I found him abandoned. Just recently in the last couple of months, he has run off to a neighbor farm and is living in an old abandoned house trailer. The trailer is about 250 yards from our place. I have brought him home 5 times already. When I find him in the trailer he's always exactly in the same spot just lying there. He will come to me each time and when he gets home, I put him in the tack room and feed him canned food and he eats like he is starving. If I allow him out of the tack room he will go right back to the old trailer. My tack room is huge with litter boxes, heated cat beds and free feeding. I cannot figure out why he keeps returning to the old trailer where there is no water or food for him. He's maintaining his weight because I go about every 3 days and bring him home. ANY SUGGESTIONS?? Can this be stopped? I want him to stay home where he's safe and loved. There are no fights other than play between my cats and they have over 16 acres and a big barn to stake out territory. Any help would be appreciated!!!!
