Two cat videos for a better Monday!

(CBS) - Every Monday needs an infusion of cat videos to lighten our day. For this Monday, videos of mesmerized cats take the cake.

We all know cats chase mice, its natural. But what happens when a cat named Murray encounters a digital mouse, on the screen of an iPad? Will instinct kick in or will the digital rodent look unappetizing? Check out the video above to find out.

This confused kitty cannot figure out how these mice keep on getting away. They move and squeak just like a real mouse would, but whenever Murray the cat goes to grab them they disappear! Murray seems to figure it out a little bit that the mice aren't real around the end of the video, but at least Murray gets some good reflex practice before going after the real deal.

The second cat video, below, shows Rikki the cat who apparently is a very tough cello critic. Rikki is as tough a critic as they come in the cello world; disturbing practice and making you start over whenever there is any sort of mistake or slip up.  Watch and see.
