While looking up the names of the people who wrote the hymn "My Faith Looks Up to Thee", I found this video of a feline who appreciates acoustic guitar music (or maybe it's the 15 seconds of fame).
This musical cat is not to be confused with Cats, the musical or Cat's Music.
There is music specifically for cats and music videos that remind us to "stop littering".
And there are numerous blogs about cats.
But my favorite online "kitty treats" have to be The Daily Kitten and I can has cheezburger.
