My cat likes boxes, no, not likes them, she loves them, they all belong to her, at least in her not so humble opinion. I got a box of photographs delivered and after I took the pictures out she had to get right in. "Who says I don't fit? I fit just fine, see!" Forget the back leg and tail hanging out over the edge..
She is nicely posed in front of some storage boxes I just covered with contact paper, thus the nice granite like background ;)
