Kitty's do that sometimes...I'm sure he'll come back to you eventually. I wolud try playing with him a lot. If that doesn't work, ignoring them works!! Noah does the same thing to me! If I'm gone for a few days and my hubby is there Noah pretends to like him more than me. (I swear he is pretending! ) After I finish loving him to death and not getting anywhere, I decided to ignore him....it only took at few hours and I had my old Noah back. Cats are so coy sometimes!
