OT book – Eliot's cat 'famous in proverb and famous in rhyme' (11)

I believe the answer is:

deuteronomy

(Other definitions for deuteronomy that I've seen before include "OT book" , "Old cat in T.S.Eliot's" , "Fifth book of the Bible" , "Book of the Old Testament" .)

I've seen this clue in The Guardian.
