Cat, Cubed

Dru sent Daya a really amazing birthday present.
It arrived in a box, as do many packages.
It is perfectly cat-sized.

Isis is addicted to the Box, and has taken mostly-sole ownership of it.
Pebbles occasionally gets to sit in the box.
Furball has never gotten a chance to sit in the box but she seems ok with that.

When Isis is in the box she is a cube-cat.
She does not mind where the box is, as long as she is in it. Daya and I have been having fun sliding the cat-filled box around. Isis does not mind going for a ride.
