Fight Against A Fractious Feline: what a glorious cacophony haha, really fitting for some boss fight. That instrument kinda sounds like "Meow", so very fitting.
Cranky Cat: Could have used some more dissonances I think to make the cat grumpier, but very cute.
Kitty Cafe: Love the bossa style rhythm, great choice for a coffee house.
My little World of Cats: Very cute tune once again. Would definitely fit in a NES game.
