... as he grow older, he like to sleep on the sofa even more.. Now the sofa has become his bed.. Am thinking maybe the sofa have bigger space than his sleeping chairs that why Tiger like sofa better.. He is definitely not liking I sit on the sofa while he is sleeping and annoy by me taking his sleeping pattern.. Tiger has been very comfortable with me, how I know? he has shown so so many sleeping pattern. Time for me to go to sleep too!
