As you may know from some of my previous posts, I'm a big Doctor Who fan. And now, my cat Milo is too. My awesome husband build this kitty TARDIS so that Milo could have a place to climb away from the baby.
He was inspired by this design, but created his own piece. There are multiple levels and it is open on the side to allow for delightful sunbathing. Milo is pretty happy. Just don't tell him it doesn't really travel in time and space.
