I think I have the only cat in the world who hates being stroked 
He is 18 months and I've had him since he was a 3 month old kitten. When he was young I thought he may grow into affection but he still hates being stroked, never rubs himself on people's legs, won't sit on my lap etc etc.
If anyone strokes him he will try and nip their hand.
It is quite sad, I love him but I meet lots of other cats who love affection and being petted, when I got a cat I was hoping he would be some nice company and be one of those cats. I wanted a cat that was mine for so long to have this bond and he just doesn't want to know.
He does sit in the room with me but always beyond touching distance. He will only come to me when he wants food, and even then he will bite me for attention.
Are some cats just like this, is this just his personality and unlikely to ever change?
He does have lots of treats, toys, play time, garden time etc so he is not deprived or depressed.
