I have no clue how this photographer got these cats to where hats and sit still. I guess some cats are just blessed with an easy going demeanor and others are not! The hats pictured above are available on amazon if you want to go ahead and buy one right away.
I am sure this would also be a super easy DIY project for those of you with just a little bit of sewing skills. Unfortunately I was not able to find a free pattern. You can always live a little and splurge on an order at amazon!
