A Cat That Heels?

I know it sounds funny, but it's true. My brother and his sons live next door and they have a few cats. One of the cats (Captain Jack Sparrow - yes obviously named for the Johnny Depp character from Pirates of the Caribbean) walks beside me whenever I walk between our house and my brother's house. It's not your standard cat under your feet walk, this little fellow walks in a perfect "heel" just like a dog that graduated with honors from obedience school. To the best of my knowledge no one taught the kitten to do this, he just does it. I'll have to try and get a video of it some day to put on YouTube.
