Aww my kitten hocus was just like this when we got her it was so frustrating but it has taken a month and now she is happy to be stroked and sometimes cuddled but is no longer scared of us !
I separated her from my other cat for an hour a day and just spent time playin with her and to start with just sittin in the room and giving her afew cat nip drops evey so often she soon learnt that strokes are quite nice ! she cant resist playin with a bit of string thou so that mit be a good way for you to start a bond good luck !!!
