This is Lucky, my 16-year-old tuxedo/Turkish Angora cat. He REALLY REALLY REALLY loves his catnip. He doesn't go insane and run all over the place, but my Maine Coon always did (R.I.P Merlin). I also have a Siamese, Bobo, who hides under the bed all day and comes out at night.
Anyway if you pay attention, you will notice that near the end of the video, Lucky actually LICKS the camera.
