Instead of a Christmas tree, these kitties got something different this holiday season. Their human built a 5-story tower made from pure cardboard and named it 'the Empire Cats Building'!

"I made a lot of toys for my cats and kittens before. This time I decided to construct 'The Empire Cats Building,'" the human said.

What a great idea! And just think about how much I have spent on cat trees... It's time to build my own.
