1/2
[Heck yes I know the one and what has Sebastian done lately to be so lucky as to experience suffocation by cat?]
Sebastian!
[He's concerned for all of two seconds until he hears what might be tiny growls coming from the kitten's teensy lungs or...Sebastian making happy noises? Honestly, they'd probably sound the same to him and he's not sure which one he'd rather it be. Either way, Sebastian's completely useless now unless Ciel steps in, so he figuratively does just that.
He releases his grip around Sebastian's collar, gripped in a moment of panic when the kitten made its sudden leap, and tries to pry the kitten off Sebastian's face. Of course, the kitten's perfectly happy where it is, so fearsome while defending Ciel's honor, so it refuses to budge.]
