But if you listen closely when he  hears someone come in and retracts his claws, you hear the sound  effect of Wolverines claws extending (if you listen closely, you  can tell the difference, as the retracting sound is the same as the  extending sound, but played in reverse), and then the cat crying  out. This was an unintentional moment of comedy which was going to  but cut but the last minute decision was made to leave it in.
