The good news is the video wasn't taken down. The bad news is the channel can't make any income from ads on that particular video unless the owner challenges and wins.
So you may be asking yourself, how did something this ridiculous happen? Here's a quote from the following blog post:

According to YouTube's Content-ID system both EMI Publishing and PRS own the rights to a 12 second purring loop.
Yep, that's right, now corporations can claim to own animal sounds too. When will the exploitation of the Youtube copyright claims system end? Does everyone need to move over to some other video hosting service for Google employees to realize this kind of nonsense will not be tolerated?
