Mystique enjoying her Christmas Box

We have three cats, but I only made up two of these boxes. That was because our cat, Mystique, likes to sleep in the puppy beds. She seemed to take a liking to the wrapped boxes. Therefore, I wrapped up one for her (cut the hole first) and now she is enjoying hers. 

The cats like to investigate new things around them. I may end up wrapping the boxes in various holiday wrapping paper or even holiday fabric. 

Starch or a washable glue can attach the fabric to the boxes. I can always wash the fabric when it gets dusty.
