There is a reason why we should save boxes for cats. They absolutely adore them. Who would think the inexpensive, average looking paper material would be such a fun toy for the furballs to play with.
The video below shows three lovely kittens playing with a tissue box. One gets stuck in the box where the other two are trying to get in too, but it just does not fit them all. :-) Don't you just love how kittens play together. They are as cute as buttons.
Enjoy the video.
