Your white and orange cat reminds me of my younger cat Tails. Not only are they basically identical, but Tails also prefers to be the one standing and lunging vs laying down and being defensive.
Love the music! Tiny would love to have a playmate like that. Christy's just not into the rambunctious play, poor girl. She'll get to the "Hiss!" stage before Tiny's had anywhere near enough.
