Harry Frees is the photographer responsible for these legitimate old time-y portraits of kittens and puppies that you've probably seen somewhere on the internet. He began dressing animals in tiny human costumes all the way back in 1905. You can imagine how hard it must have been to take a clear photo of hyper kittens with a camera back then! You can read more about his story over here.
Sorry Corduroy, you've been dethroned by a Siamese kitty from Texas. Believe it or not, Scooter is 30 years young and still kickin'. You can find out more about him over on the Guinness World Records website.
