I lack a knowledge of the language used in this song, so this is just a guess: a thumb is in love with a cat. Both have human mouths superimposed either digitally or biologically (please let it be digitally) on them so that they may profess their love for each other. This is Vitaliy Shakirov's "Salvador the Singing Cat." It will be stuck in your ears and your nightmares for the next week.
You're welcome.
