We were inspired by a post on Cole & Marmalade's blog to make a "cat cave" out of a t-shirt and cardboard box. (Scroll down to see the article on their site.)
We used a t-shirt I found at the thrift store, because I thought the pattern would look cool.
Just stretch it over the box and knot in the back!
Ringo was very curious about this.
He went in for a moment, but came right back out.
He ended up sitting right *outside* of it, silly boy.
No one has taken any interest in it yet. We'll try different locations and see what happens.
