1. Silence - we thought silence wouldn't be more effective than sound, when the cat is seen. It adds to the 'unknown' and the mystery.
2. Production name, Enigma - this goes with mysterious characteristics of the cat and it also links in with thriller conventions, of creating an enigma.
3. Sound - having silence all the way through became a bit boring, something else was needed to keep the audiences attention, we chose to put a little bit of sound as 'ENIGMA' came up. It is also quite a mystical sound which goes with the rest of our ident.
