Casey is like that too, he'll try to get into a box that is much to small for him.....it's too funny......but any box that is big enough to fit him, you can guarantee that he'll be in there.....he likes to jump in the empty clothes hamper too...he did the other day and I carried him around in it for a good 5 mins before I had to make him go out so I could get more clothes out of the dryer to fold....silly silly kitty
