Ginza loves to stick his head into boxes, here's one of his favorites, cause he can see thru the other side. Of course the toy that was in that box is ignored. He then crouches very still like that....does he think he's hidden and we can't see him?
I love seeing the interaction between the sibs, they have stayed close for these 2 1/2 yrs. They play together, snooze together, groom one another, etc.
And they seem to treat each new cat as another sib to play with! They are so well socialized; they ought to be, we held them (and kissed them and told them how wonderful they are...)every day since birth.
