"Has your cat died?

[tartan]

What does the saying "Has your cat died?" mean

[heathfield]

It means your trousers are too short in the leg, and it looks like you're wearing them at 'half-mast', as you would fly a flag as a sign of mourning.

'Trousers too short' is what it means - nothing about miserable!
