That time Steve Martin infamously ironed a kitten. Was a huge scandal.
Just kidding. Pretty sure this is the same white cat.
Yep. He knew this cat!
Before he was a star, Steve juggled kittens for money. It's in his book I Once Juggled Kittens for Money.
Awww. This one's sweet.
There's no cat in this one but I thought you'd want to see what Steve Martin woulda looked like as a rock star.
Steve loves cats so much he lets them drive his car sometimes.
I can see it.
This isn't Steve Martin. It's David Bowie. So what. It's my thread.
Of course Johnny Cash loved cats. I'd expect nothing less.
Aw. Andy Samberg plays with his kitty.
Love Nicolas Cage, love the cat, love the coloring.... don't love the pose they went with.
Love this shot but it's clear that this cat doesn't enjoy being held. 
This image belongs in The Louvre.
Halle Berry, cat woman
Sigourney Weaver hugging her Alien co-star between takes.
Cute poster except they used an image from Aliens. Ripley's hair is long in Alien, short in Aliens. #nerd
