They've been rolling around on the floor attached to each other for the past 20 minutes, glaring at each other, the big one growling's resembling that of a tiger, the little one's batting her paws against the big one's ears.
Here's the big one: "rrrrrrrrrrrRAARRRR-RAAAAAARR-hsssssssssssss-grrrrrrrrrrrrrrr *grabs little one by the head and tries to bite her*"
Here's the little one: "Meh *pats the big one's ears* Ehh" (keep in mind she's a little kitten, so it's more like a struggled squeak than an actual meow. Kinda cute in fact, her jaw kinda shakes as she squeaks)
