Sound Possibilities

The most important sound in my animation should be the "meow" at the very end. Another sound effect I had in mind was the sound of coins dropping which would give the lion a fright, but then he'd be intrigued which leads him to jump out of the coin frame. I was thinking that it would be a good idea to add the sound of glassing smashing in the empty frame after the cat runs across the screen for comedic value. I'm still debating whether I should have some sound as he's running like paw steps. I'm also debating whether I should have some kind of song during the titles, I was thinking a crackly old fashioned version of 'Rule, Britannia" which could then suddenly warp and cut out like a record player suddenly being stopped as the coin rolls in.
