Munkustrap
'Are you blind when you're born?'
Munkustrap is a gray, white & black tabby tom. He's sort of the leader of the tribe: second in command, I suppose. He & Demeter seem to have some sort of relationship, though I've heard that it's Alonzo in other productions. Munkustrap has been said by many to be Mistoffelees' brother, Grizabella's son, Macavity's brother, etc. These theorys are certaintly plausible...
Munkustrap has a lot of singing. He sings most of the play, actually, including the narration for The Awefull Battle Of The Pekes And The Pollicles, the play within a play that the cats perform for Old Deuteronmy. He sings many other songs beside, so I'm not gonna list them all. He sings the filler, between song parts, among others.
Actor's who've played him: Michael Gruber (video), Abe Sylvia (Broadway), David Ashley (London)
