It've happend to me too a few years ago,
he's dead now but he was all abandooned behind our house, it was one of the most cuddeling cat we have ever got so far,
if you did start to stroke his fur he did climb up your leg and stoped at your shoulders,
where he did start to walk from shoulder to shoulder and stroking his whole body against your head so he could cuddle :3 you could walk like 1kilometer with him up there he wouldn't mind :3
