Oh I had a boy who did the SAME thing! He was VERY independant, never kissed me, cuddled with me, actually he never sat still for more than 30 seconds HAHA then he got fixed when he was about 6 months old and since then hes a total snuggle bug. Overly done but still a 180 turn around in personality. He is ALWAYS pawing at me to pet him, jumping on me to pick him up and hold him, he wants to be held and cuddled 24/7! (like I said, overly done but hes sooo cute!) he never was a big 'kisser' and hes still not really, but he will 'bathe' me sometimes! COVER one area with kisses for like 10 mins til I have to make him stop! haha He is now almost 2.5 years old and he never went back to his unaffectionate state.
