Catfancy.............I was speaking only of the possibility that Mr Raggs living outdoors. I must admit to not properly reading the spare room idea. (I am sometimes a bit dyslexic). I will not actively say that life in a spare room is bad. It could be better than a shelter life especially if the shelter uses cages. But cats are extrememly curious about what is on the other side of closed doors (trust me on this, I KNOW). And he could slip out or they could slip in and if a fight occurs immediately, think of the worry you'd have to live with. But I stick by my statement that outdoors is NOT a good place for him as it is unfair to this and future generation of strays and ferals.
And I do not say your decision is easy, it is probably one of the hardest to have to face, but if you really love someone, you need to let go some times.
