Recently we uncovered video footage of what the Guinness Book of World Records says is the longest cat in the world. She's 48 and a half inches long and belongs to a couple in the US.

But last night on 'Conan,' Conan O'Brien disputed the couples's claim and showed viewers the actual longest cat in the world.

If you weren't a dog person before this video, you will be now.

Which is the world's longest cat? Watch Conan's take, and the original video, below.
