It's hard to say where or when inspiration will strike. I find myself trying hard to rationalize my inspiration when it's for something exceptionally silly.
Take my Birds in Heels, for example. For some reason, birds wearing bright red high heels struck me as funny at one point, and I had to do something about it.
And now this... I can't even really say how this came about, but it turned into a cat with a hopelessly touristy fashion sense, setting out to see the world. He visits all the gift shops. He can't leave until he has a photo of himself in front of wherever he is. He's not very original with his poses. He has lots of frequent flier miles. He never steals hotel towels, but he just can't resist those little bottles of shampoo. Maybe you'll see him hanging around your favorite monument someday.
Have a good photograph of somewhere you think Claude the traveling cat ought to visit? Send it to me, and Claude just might fancy a trip. He'll send you a postcard when he gets there.
