A cat looks at it's iPod with head phones in at a list of playlists that it's created. The different tracks are various different stimulating sounds for cats: can opener, door latch, birds, cat nip bag.
That cat has it made.
Our cat has “Geckos Skittering Up the Wall” on her playlist here in the Philippines.
Fancy feast bag..climb the curtain
Some of those tracks must be very short.
